Trends in mining machinery

With social progress and economic development, human resources and the demand for energy is growing, while China is a  Mining vibrating screen relatively resource-poor countries. Automated unmanned

underground or dangerous working face is the development direction of the mining environment, but also protect the safety of mining face an effective way. Integrated use of

mining science, automation technology, China Vibrating Screen communication technology, computer science and technology, automated unmanned working face fundamental research and development of new

technology, new equipment, so that mining machinery (crusher) will be toward the robots and intelligent direction. Bears a variety of strategic metals seabed mineral resources,

to achieve safe and efficient marine mineral resources exploitation, to protect the country's maritime rights and interests and to provide technical support for national

economic development, sustainable development of society to provide protection. Achieve seabed mining, development of deep-controlled unmanned submersible submarine, homemade

unmanned untethered submersible other intelligent mining machinery and equipment.
Mining machinery (crusher) the overall level and international advanced level there are still gaps. Towards mining machinery (crusher) journey in manufacturing power,

opportunities and challenges. Product design is the soul of manufacturing, product structure, function, quality, cost, delivery time and manufacturability, maintainability,

scrap reprocessing and human, machine and environment relations, in principle, are in the product design stage decision. Product innovation design capacity has become deciding

the status of competition in the global primary factor.

How to maintain mining machinery

Mining machinery costs are too high, so we bought the equipment properly maintain it so that life can be longer mining machinery, contain all harmful factors.
First, to reduce the impact of mechanical dust
Mining machinery dust generally refers to the daily work generated dust, debris and other non-metallic materials, soil material and mining machinery manufacturing some of the

metal shavings, wear debris, etc. Once the debris inside machinery and equipment, with the arrival of machinery between the surface, the harm is great, not only block out the

relative motion, will accelerate the wear and tear of parts, and will scratch the mating surface, destroying oil mill, prompting parts coal crushing plant temperature, lubricant deterioration Jaw

Crusher . Therefore, for mining machinery working environment, a quality to be used, and the supporting parts and lubricants, greases, blocking harmful substances at source. The

second is to do a good job-site mechanical protection role in ensuring that the various parts of mining machinery to work properly, prevent all kinds of debris into the

machinery inside, resulting in poor mechanical damage of mechanical failure, try to go to the regular maintenance of plant repair, on-site repair, must be prepared to work to

prevent parts repair site into mechanical components pollution.
Second, to reduce the effect of temperature
In operation, the temperature of each individual component has the normal range, such as, the general temperature of the cooling water are generally in the 80-90 ℃, the

hydraulic system is generally at 30-60 ℃, below or exceeds the zero will cause Parts of accelerated wear, causing oil deterioration, resulting in changes in the material

properties of the small ball mill, etc.,
For this reason, in the course of mining machinery, a low temperature to prevent overload, low pre-heating stage to ensure the normal operation of the mechanical reach the

required temperature before for traveling or working, not because it was not a problem while ignoring its important role; Second, we must prevent the mechanical operation at

high temperatures, mechanical operation process should always check the value on a variety of thermometers, found the problem immediately shut down for inspection, found fault

immediately removed. For unable to feeding equipment a reason, absolutely can not treated and still make mechanical work sick crusher. In the usual work, pay attention to check the cooling

system is working. For water-cooled machines, must be checked daily before work, add cooling water; pair of air-cooled machines, but also regularly clean the dust on the air

cooling system to ensure smooth flow of cooling air duct on the roll break.
Finally reduce all kinds of corrosion
Metal surface and the surrounding medium chemical or electrochemical action destroyed the phenomenon known as corrosion. Such corrosion will not only affect the mechanical

appearance of the device's normal work, but will corrode to the mechanical parts inside the classifier. Such as rain, airborne chemical substances through the mechanical parts

of the external channel, cracks, etc. into the internal machinery, mechanical parts internal corrosion, accelerated mechanical wear and increase mechanical failure. Because of

this corrosion is sometimes invisible, intangible, easily overlooked panties, and thus greater danger crusher. In use, management and operations staff to the prevailing local

weather conditions, air pollution, and take effective measures to reduce the impact of chemical corrosion on the mechanical, the focus is to prevent rain and airborne chemical

composition of the intrusion of mining machinery.

Talk about the advantages shaker

Mainly by the sieve box, exciter, suspension (or supporting) devices and electric motors and other components. Electric shaker machine via V-belts, drive spindle rotation

shaker, shaker on the uneven weight of the centrifugal force of inertia, the vibrating screen box. Changing the eccentric weight exciter,

Obtain different amplitudes.
Shaker main advantages:
1. As strong vibration sieve box, reducing the material clogging the sieve, thus making a sieve with high vibrating screen manufacturers efficiency and productivity.
2. Simple structure, easy removable screen surface.
3. Screening of electricity consumed per ton of material less.
Mechanical
Shaker generally vibrator, vibrating screen supplier, supporting or suspension, transmission and other components.
Vibrator shaker
Uniaxial and biaxial shaker shaker vibrator, eccentric weight configuration according to generally distinguish between two
Patterns. The eccentric weight is configured to block the eccentric type is better.
Screen box

Screen box from the screen frame, the screen surface and the clamping device components. Screen frame is constituted by the side plates and beams. Screen frame must have

sufficient rigidity.
Support means
Shaker with hanging support device and seat two. Seat-mounted relatively simple and low installation height should generally be preferred. Shaker supporting device consists of

elastic components, commonly used a coil spring, a plate spring and rubber springs.
Gearing
Shaker usually belt drive means shaker simple structure, can choose the number of revolutions of the vibrator, but is easy to slip the belt is running, may cause clogging the

sieve. Shaker there is also a direct drive coupling. Couplings can remain stable vibrator

Number of revolutions, but life is very long, but the number of revolutions vibrator adjustment difficult.

Shaker working principle and characteristics

Works
Linear vibrating screen work, two synchronized reverse rotation of the motor exciter excitation force generated reverse, forcing driven vibrating sieve sieve sieve longitudinal

movement to do so by the exciting force on the material is periodically thrown forward a range, thus completing the material Mining vibrating screen operations. Suitable

Sand and gravel quarry screening, but also for coal preparation, mineral processing, building materials, electricity and chemical industry for product classification purposes.
Shaker working part fixed and depend on the material slide along the face leaving materials are sieved. Fixed grizzly is more of a concentrator applications, generally used for

rough broken or crushed before the China Vibrating Screen process. It is simple in structure, easy to manufacture. Not consume power, can be directly put mine

Stone unloaded onto the screen surface. The main disadvantage is the low productivity, screening efficiency is low, generally only 50-60%.
Shaker face by scrolling horizontally arranged shaft consisting of a root, shaft with plates, fine material from the gap between rollers or plates through. Bulk material from

one end of the roller driven to move to and from the end of discharge. Concentrator rarely use this sieve. Shaker work

Part is cylindrical, around the cylinder axis of the rotary screen, the axis of the general inclination of downloading into. The material fed into the cylindrical end of the

fine material from the cylindrical working surface level through the sieve, coarse-grained material is discharged from the other end of the cylinder. Cylindrical sieve speed is

very low, the workers

For stable, good power balance. But its easy to plug the sieve screening efficiency is low, the work area is small, low productivity. Concentrator rarely use it to make

screening equipment. Shaker body is a plane swing or vibration. Its flat trajectory is divided into linear motion, circular motion,

Elliptical motion and complex motion. Shaking sieve and shaker in this category. Shaker work, two-motor synchronous reverse placed so that the exciter excitation force generated

reverse, forcing mesh sieve to make longitudinal movement led to the material by the exciting force and periodically thrown forward a range,

Thus completing the materials screening operations. Crank shaking sieve is used as transmission components. Motor through a belt and pulley driven eccentric shaft rotation, so

that the body by connecting rod for reciprocating movement along a certain direction.
Body movement perpendicular to the center line of rods or suspension rod, the oscillating motion of the body, the screen surface material to a certain speed to move the

discharge end, the material also be sieved. Shaking screen with the several sieve compared to its relatively high screening efficiency and productivity. Its lack of

Dynamic equilibrium point is poor. Concentrator now rarely use it, while being more structured shaker replaced.
Work characteristics
① using block eccentric as excitation force, strong exciting force.
② sieve and screen box beams using high strength bolts, simple structure, convenient maintenance; shaker ③ The tire couplings, flexible connection, smooth;
④ the use of small amplitude, high frequency, large angle structure of the machine high efficiency, handle the largest, long life, low power consumption, low noise

electromagnetic vibrating feeder by transmission mode of the right and left type transmission type drive, along the running direction of the material, the right of the drive in

the machine for the right type transmission,

And vice versa for left-type transmission.

Dual pull feeder can be used for tobacco production line silk

Feeders are widely used in metallurgy, coal, chemicals, building materials, light, glass, food, food, tobacco, abrasives, abrasive and other fields. Feeders called feeder,

feeder material can be horizontal screen divided into groups, double pull feeder, feeder wheel, disc feeder, screw feeder

, Automatic feeder, vibrating feeder.
        Dual pull feeder can be used for tobacco silk production line, the transportation of materials for different manufacturing processes. Play a regulatory process flow, to

prevent excessive fluctuations in flow, balanced production role.
        Dual pull feeder start working in automatic mode, the first silos with steep angle conveyor belt running simultaneously, the regiment began to transition material feeder

buffer silo cloth, when the transition Screen machine point buffer silo approach to enhance the material layer increased its high material level was detected when the photoelectric switch,

storage

Silo conveyor belt speed is reduced, when the transition point buffer silo approach to enhance the material layer is reduced to its disc feeder switch undetectable when silos

conveyor belt speed, and so on; when the transitional buffer silo entrance increased material layer material was its high bit photoelectric switch detects when

, Silos feed conveyor stops, when the transitional buffer silo entrance to the material layer is reduced to undetectable impeller feeder switch when the group started feeding

material feeder, when the photoelectric switch level position adjustment appropriate storage material start and stop frequencies warehouse conveyor can be greatly reduced, then

the impeller feeder

Feed rate is slightly larger than the steep angle conveyor lift, improve quantity kept at minimal.

Screw feeder production efficiency third

      Miniature screw feeder mainly by the mixing console, material weighing system, material handling systems, material storage systems and control systems and other five major

systems and other ancillary facilities into. Since bucket chain feeder metering and metering station aggregate reduction compared to four intermediate links, and is a vertical

Direct feeding measurement, saving the mining screen measurement time, thus greatly improving the efficiency of production of the same model in the case, the screw feeder screw feeder less

efficient than the one-third of production efficiency.

Miniature screw feeder system is affecting the quality of concrete and concrete production cost of key components, mainly divided into aggregate weighing, powder and liquid

weighing vibrating screen classifier weighing three parts. Under normal circumstances, less than 20 cubic meters per hour, mixing station using superposition weighing methods, namely Auger

Feeder with a scale, cement and fly ash with a scale, water and liquid admixtures were weighed, and then put into the water, said liquid additive pre-mixed bucket. In more than

50 cubic meters per hour, mixing station, the use of the said material independent way of weighing, weighing are all taken

Electronic scales and computer control. Screw feeder weighing accuracy ≤ 2%, cement, powder, water and admixtures are up weighing accuracy ≤ 1%.

Screw feeder conveyor consists of three parts. Aggregate conveying; currently bucket chain conveyor with hopper feeder conveyor and belt conveyor in two ways. Screw feeder to

enhance the advantages of small size, simple structure. Belt conveyor has the advantage of conveying distance, high efficiency, it is

Barrier is low. Belt conveyor is mainly used to bucket chain feeder temporary positions mixing station, mixing station to improve productivity. Powder delivery; concrete powder

Type stirring floor scraper conveyor with pneumatic conveying and the. Miniature screw feeder has the advantage of simple structure, low cost, and reliable. Liquid transport

mainly refers to water and liquid admixtures, they were transported by the pump.

To explain to start the process of screening machine

       It is understood that the process of screening machine is starting up work from stationary eccentric mass angular velocity w, then the screening machine with angular

velocity w for stable operation. Therefore, when starting mining screen, maximum torque output of the motor. Since mc ground is relatively small, approximate calculation can

be ignored. Load characteristics and m is not a constant value, the vibration of a cycle, when the mass of the vibration movement from the bottom up, the motor will be greater

energy output; down by the quality of the vibration movement, it will emit energy.
  
        In this case, the supply current will be affected. However, because of the rotary member vibrator has a large flywheel effect, the load on the motor tends to be smooth

and uniform. Taking into account this factor, when starting the sieve maximum static torque must be multiplied by a coefficient K. Generally does not allow the motor starting

time is too long. So it can be used as a rail equipment selection. Some countries in the shaker motor selection, there are certain requirements for the start-up time. In shaker

design calculations, generally allowable starting time can be slightly higher than the recommended starting time 1 ~ 2s.

         The maximum torque of the motors in general about 2 times the rated torque. Therefore, in the calculation and selection of motor power, its rated torque can be

approximated by the maximum torque to select, but also consider the circuit voltage drop. In the beginning, the acceleration is constant or nearly constant, the motor power

consumption, in addition to generating speed torque, the most of the power is mainly consumed in overcoming static torque. Then through the resonance zone, the steady state is

entered.

On the import of used excavators crusher equipment status audit

Compared with the previous, the acceptance of emphasis on the import of old feeder feeder excavator equipment status of the audit. Imported second-hand excavator in management,

in fact, as early as 2005 authorities had already formulated the "imported second-hand excavator acceptance norms"

On imported second-hand excavator emissions, noise, crushers make provisions for warranty period, imports of used excavators raise the stone screening machine threshold. However, in 2006 the Ministry

of Commerce issued Notice crusher management point of view, these provisions are not used excavators emphasis on performance audits.

Admittedly, the second-hand excavator acceptance of norms to help domestic enterprises to expand sales of new machines, but not all do not meet the acceptance of used

excavators. From the Research Institute and author of feeder manufacturers and other aspects of understanding point of view, they think, "30%

The alternative proportion "is a more objective assessment, then, if the 2010 excavator imports 28,000 units as the basis of Circular vibrating screen measurement, 30% of the alternative rate is intended

to mean that in 2009 the domestic feeder machine business can additional 8,654 units of market capacity by Shan Ha Ji crusher

Energy, Liugong and Sany Heavy Machinery 2008 3.64%, 3.27% and 4.13% of the excavator market share to estimate, respectively, this year is expected to bring the enterprise

feeder 315,283 and 357 units sold.

Vibrating sieve is divided into several levels of various raw materials

Shaker many types commonly used in mineral processing industry according to their structure and motion characteristics can be divided into the following types:
         1) Fixed Screen: Includes fixed grizzly fixed bar screen, cantilever bar screen, ZS linear shaker and curved screen.
  2) Jane shaped sieve: a cylindrical sieve, sieve cones and pyramids.
  3) Circular Vibrating Screen: Graphic shaking sieve.
  4) shaker: Mechanical transmission systems and electric drive of two kinds. Belonging to the former eccentric screening equipment , Vibrating Screen, self-centering vibrating

screen, vibrating screen and resonance sieve. The latter have electric vibrator sieve.
  5) probability screen: including rotating probability screen, vibrating screen, and so thick probability screen, circular vibrating screen.
  6) ZS vibrating screen: including curved screen and high-frequency screen and so on.
  Vias through the sand vibrating screen surface material called vibrating screen, vibrating screen is a kind of a variety of raw materials and primary products at a variety of particle size

material is divided into several levels, or to the moisture and impurities removed, then the next step processing and improve product quality mechanical equipment used when

Equipment.

Screening machine to achieve synchronous operation is the goal of their industry

        It is understood that circular vibrating screen mathematical model for dynamic analysis. Let sieve centroid in x, y coordinate origin 0, only along the x, y-axis

vibration in the x, y plane without rotation. Vibration system in accordance with established principles of motion Alembert differential equations, at any moment acting on the

sieve on the inertial force, damping force, elastic force and the centrifugal force of the force is zero. Therefore, building sand production line can be used. Kinetic analysis

of linear horizontal screen - two degrees of freedom vibration system.
   
        Linear vibrating sieve vibrator has two eccentric mass, the work reverse constant rotation, and two eccentric mass and equal eccentricity. In the vibration direction,

the exciting force of the centrifugal force generated by two of the eccentric mass and; vibration in the vertical direction, the force is zero. Thus, the vibration screening

machine direction of reciprocating linear or nearly linear vibrations. In the self-synchronous linear vibrating screen, in fact, between the two eccentric mass, damping

differences that exist, the motor drive characteristics are also minor differences.

       Therefore, the starting process in a shaker, the two eccentric mass is often not completely symmetrical in position, and there is a phase angle difference. However, since

the vibration direction of the vibration acceleration around the center of gravity and the oscillating sieve acceleration of the inertia force generated, will form a chase and

chase torque forces, the two eccentric mass produce chase procedure, and ultimately the synchronous operation of the Vibrating screen. The mathematical model of this motion.

Assuming the quality of the vibration shaker focus on the center of gravity, by the coordinates x and y to determine the movement of the plane of movement.

To explain to start the process of screening machine

       It is understood that the process of screening machine is starting up work from stationary eccentric mass angular velocity w, then the screening machine with angular

velocity w for stable operation. Therefore, when starting mining screen, maximum torque output of the motor. Since mc ground is relatively small, approximate calculation can

be ignored. Load characteristics and m is not a constant value, the vibration of a cycle, when the mass of the vibration movement from the bottom up, the motor will be greater

energy output; down by the quality of the vibration movement, it will emit energy.
  
        In this case, the supply current will be affected. However, because of the rotary member vibrator has a large flywheel effect, the load on the motor tends to be smooth

and uniform. Taking into account this factor, when starting the sieve maximum static torque must be multiplied by a coefficient K. Generally does not allow the motor starting

time is too long. So it can be used as a rail equipment selection. Some countries in the shaker motor selection, there are certain requirements for the start-up time. In shaker

design calculations, generally allowable starting time can be slightly higher than the recommended starting time 1 ~ 2s.

         The maximum torque of the motors in general vibrating screen classifier about 2 times the rated torque. Therefore, in the calculation and selection of motor power, its rated torque can be

approximated by the maximum torque to select, but also consider the circuit voltage drop. In the beginning, the acceleration is constant or nearly constant, the motor power

consumption, in addition to generating speed torque, the most of the power is mainly consumed in overcoming static torque. Then through the resonance zone, the steady state is

entered.

Introduction often used in screening machine eccentric shaft

        Screening machine used in bearings, after years of practice, that the choice of three groups and four groups clearance more appropriate, that a large clearance bearings.

Clearance in each group, the size of the radial clearance values, according to the bearing diameter varies. Commonly used stone screening machine bearing diameter, usually in

d6s ~ 4180mm range greater. Bearing running clearance, the bearing radial clearance than small. It is subject to the assembly line with the nature and the operating temperature,

etc. due to the impact of cable.

        The so-called mill running clearance, after the bearing assembly is, in operation, the bearing ring and the gap between the rollers. Running clearance should generally

be greater than o. Screening machine vibrator working state, determines the load bearing states. As commonly shaker rotating eccentric block or partial

Mandrel as excitation source, so the bearing outer ring subjected to cyclic loading, a fixed load bearing inner ring. Meanwhile, the dryer manufacturer that due to their higher

operating temperature, thermal expansion to compensate for parts, shrink. Thus, dewatering screen  bearings with a one certain characteristics.
   
      Broken stone gravel production line in some countries, in order to prevent the bearing outer ring and housing between the sliding interference fit. Such as pore size less

than 15 0mm, using N6; against big aperture 150mm, using P6. The inner ring of the bearing and the journal with, a loose fit

. Such as the journal is less than 80mm, the use of g6, big 80mm for the journal, the use f6.

Screening machine for maintenance to be equipped with safety devices

        Screening machine operation, according to need, with l0Ot press, the eccentric shaft, gears, bearings and the inner pressure. In many structures, the use of hydraulic

pump, the high-pressure oil into the shaft and the bearing inner ring with the surface, and bearing puller, remove the bearing inner ring. This

Point and double-roll crusher is sand vibrating screen somewhat different. From top to bottom on the housing, with the press or with copper Remove the bearing outer ring, be careful not to damage the

bearing housing bore.
  
        Beneficiation process in open vibrator, all parts should be numbered or marking. Vibrator bearing assembly, according to the reverse order of disassembly. Assembled

bearing outer ring, pay attention to the most outer shaft and the housing end bearing bore distance and fold open the front consistent. And

Shaft with the bearing inner ring and related parts, to assemble in oil heated more convenient. Vibrator assembly is completed, the need to maintain 1 ~ 2mm axial clearance

volume. Replacement bearings must be installed in pairs, shall not be mixed. All seals must be installed as is. Installed ventilation hood, heavy

New injection of new lubricants.

        Linear vibrating screen screening machine use and maintenance must comply with the general rules of safety technology. In the screening machine during operation, the

prohibition of any repair work on the Screening machine; parking in the screening machine for repair, open circuit knife switch, knife switch and quoted,

Description ongoing repairs, prohibit start screening machine. Transmission V-belts and pulleys, tire coupling, security guards must be installed. When you want detailed

inspection or repair screening machine, you can remove the protective cover, but the screening machine before starting, you must Kaoru reattach the protective cover.

Crusher Description and working principle

Impact Crusher is a new, highly efficient impact crusher, hammer crusher is developed on the basis of. In the cement industry has been widely used. It is mainly used for

limestone, sandstone, coal and clinker etc. hard and soft rock for coarse crushing, breaking and crushing process.

A) Impact Crusher works

Crusher Although many forms, but its working principle, performance and structural designs, which also has crushing equipment a lot in common. Crusher's working parts with a hammer two high-speed

rotation of the rotor 1. Feed material inside the block, the rotor rotation range (ie hammering area) by plate hammer, and was thrown back plate 3 high speed, once again under

attack, and then from the back plate to plate hammer rebound, continue to repeat the above process . And from the way, are there any material strike against each role. As the

material by plate hammer blow, and the back plate and the materials between the impact of the collision. Material constantly cracks, loose and crushed. When the particle size is

smaller than the back plate and the gap between the plate hammer, they were discharged.

Two) crusher crushing effect on the material, there are three main aspects:

1) Crushing Freedom

The material into the crushing chamber, immediately subject to the impact of high-speed hammer and materials between the collision, while the plate hammer and the material and

the friction between the material, so that the crushing cavity material being crushed.

2) rebound broken

As high-speed rotation of the rotor plate hammer, allowing materials to obtain a high velocity, and then hit the back plate, so that the material can be further broken.

3) grinding broken

After the two crushing effect is not broken, is greater than the size of the material discharge port at the discharge port at the high-speed rotation of the hammer grinding and

crushing.

Crusher and hammer crusher comparison between works similarly, are based on impact crushing way, but the structure and work processes vary. The main difference is: crusher plate

hammer engaged into the material from the bottom up, and throw it back to the top of the board.

Three) crusher advantages and disadvantages

1) Impact crusher impact crusher full play the role, so that the material subjected to high-speed, repeatedly blow back and hit each other after the impact, the material along

the weak part of the selective crushing, so it's high crushing efficiency , low power consumption.

2) adaptability, especially in brittle materials such as limestone is more appropriate.

3) crushing ratio, usually 20 or so high up 50-60, you can reduce the number of broken segments, simplifying the production process, save and invest.

4) The structure is simple, easy to manufacture. No significant work unbalance vibration, convenient maintenance and repair operations.

2) Disadvantages

(A) hammer and impact plate wear faster. Especially in crushing hard materials, wear faster and generally should not be used.

(2) attempts to prevent poor performance, suitable for crushing plastic and viscous materials.

(3) The operation noise, dust generated is large.

Four) crusher structure

Single rotor impact crusher

Single rotor impact crusher structure, material blocks from the inlet feed, in order to prevent material blocks when broken flying in the direction of feed inlet is equipped

with chain curtain. Feed of the material block falls above the grate, a small slit gob fall through the grate in the lower part of the chassis, large pieces of material slide

along the screen surface on the rotor. The circumference of the rotor fixedly attached to a certain height hammer rotor from the motor through V-belt drive for the high-speed

rotation. Falls above the rotor speed rotation of the feed block by the impact of the board hammer, access high kinetic energy after the collision to the back plate, then bounce

back and from the back panel, and the same in the crushing zone thrown by the rotor material to collide. By the bar screen, rotor, back plate and chain curtain composed of space

known as the first impact area; from the back plate and the rotor space formed between the second impact zone. Materials in the first impact zone by crushing impact each other,

and then again into the second impact zone crushed by the impact again. The crushed materials are lower casing unloading spout.

One end of the back plate with live chain hanging on the chassis, the other end of the adjusting screw to a fixed position. When the bulk material or hard objects caught in the

rotor and crushed between the back plate gap, leaving the back plate subject to greater pressure counterattack after the shift, the gap increases, allowing debris difficult to

pass without causing damage to the rotor. Then back plate under its own weight, but also to restore the original position, as a Linear vibrating screen protection device.

Five) major components

1) back plate

Counterattack board's role is to withstand hammering out the plate material impact, so that the material and broken by the impact, and the impact of the material after crushing

impact zone bounce back, again to achieve the desired impact crusher product size.

Back plate in the form of a lot, mainly Mansard and arc-shaped categories. Mansard back surface enables various points on the back plate of the material is approximately

perpendicular to the direction of impact, so get the best crushing effect. Arc-shaped counter surface material can block out from the back plate to rebound after the district in

the center of a circle formed intense impact grinding zone, in order to increase the freedom of the material impact crushing effect.

Back plate steel welded into general use. Its back surface with wear-resistant liner, but it can also be counter-roll or grate plates. Seam counterattack with grate surface, and

its content is less fine-grained level products, equipment, production capacity can be increased, power consumption province. But there are complex, difficult to replace worn

counter surface, wear faster and other defects.

Crusher rotor mostly using whole cast steel structure, durable, easy to install board hammer, and its large mass, to meet crushing requirements. Small and light crusher rotor

also can be welded steel plate.

2) hammer

The shape of the fastening plate hammer manner and is closely related to the work load. Hammer should be designed to meet reliable, easy handling and improved plate hammer metal

utilization requirements. Board hammer generally use high chromium cast iron, high manganese steel and other wear-resistant alloy steel. Board hammer shape many, elongated, T-

shaped, S-shaped, workers shaped, ax-shaped and other shapes with a trough, now generally elongated.

Six) crusher operation and maintenance points

Impact crusher is a kind of high speed inertia broken machinery, to ensure it is working properly and safe operation, the operator must be in strict accordance with the rules of

the provisions of operation and maintenance of the equipment to do the work.

b) the device before driving to strict inspections. The bolts are loose fasteners, easy to wear pieces are worn too large, identify problems and timely solutions. In normal

operation the device should be checked each time the sound parts, temperature, vibration and so on.

c) shall be in accordance with the car crushing equipment in the system startup drive sequence. It should be required when parking parking parking order.

d) In normal operation, you should always check the lubrication system work. Regularly add new grease and oil changed regularly. Rotor bearing temperature, normally should not

exceed 60 ℃, should not exceed 75 ℃. If the temperature rise over this limit should immediately stop checks, take effective measures to deal with.

e) feeding should be uniform, to prevent exceeding the prescribed chunks of material and non-broken material into the machine. If found to be not a normal phenomenon (abnormal

vibration and noise), you should stop and check, to identify causes and troubleshooting only after driving.

f) After the plate hammer wear should be timely replacement. Exchange must be weighed against the new board hammer selection, Wu Shi rotor has better static balance.

g) protective casing wall tree plate, back plate and bolts and other serious wear and tear should be promptly replaced. Prevent the liner and the back plate off causing serious

accidents.

h) Impact Crusher has a strong impact on the operation of the role of dust generated is large, so the crusher should be tightly sealed and well ventilated vacuuming.

i) back plate and the gap between the size of the board hammer, a great influence on the particle size, should be to keep it within the specified range, and according to the

nature of the material and the product size requirements make the appropriate adjustments.

Simple swing jaw crusher

How it works:
Simple pendulum coal mining machine fixed jaw and movable jaw, fixed jaw to the rack on the front wall, moving jaw is hanging on the mandrel. When the eccentric shaft is rotated, the

drive rod reciprocates up and down, so that the two thrust plates also come reciprocated. Through the thrust plate role in promoting the hanging

Moving jaw hanging shaft reciprocates. When the movable jaw swings to the fixed jaw, the cavity of the material falls jaw jaw mainly by extrusion and grinding. When the pendulum

away from the fixed jaw moving amount when the material has been crushed under the action of gravity, the lower jaw cavity spout free unloading. Thus jaw crusher

Machine working is intermittent, grinding and unloading process in the jaw cavity alternately. This vibrating screen design work, each point on the moving jaw hanging axes are centered

exclusively for the swing arc. Since the trajectory is relatively simple, it is called a simple swing jaw crusher, referred to as simple pendulum jaw

Crusher.

Impact Crusher Working Principle and type

Crusher (Crusher) works:
   Crusher (Crusher) using high-speed rotation of the rotor plate hammer, the material fed into the crushing cavity produces high-speed impact and broken, and the crushed

material thrown at high speed along the tangential direction of the other end of the crushing chamber back plate, was again broken, and then from the back plate

Rebounded to plate hammer, continue to vibrating sieve repeat the process. And from the way, are there any material strike against each role. As the material by plate hammer blow, and the back

plate as well as the impact of the collision between the material, the material constantly cracks, loose caused the smash. When the material finer than anti-

Strike plate and the gap between the plate hammer, they were discharged.
Crusher (Crusher) type
    Crusher can be divided according to their structural characteristics single rotor crusher (Crusher) and double rotor crusher (Crusher). Rotor steering, single rotor crusher

of reversible and non-reversible rotation rotate two types. Double Rotor Impact Crusher

Can be divided into the same direction rotary, reverse rotation type and opposite rotation type three types. According to the internal structure, single rotor impact crusher is

divided into grid plate with and without Dry vibrating screen leveling Leveling grate plate in two forms. Dual-rotor impact crusher can be divided into the rotor and the rotor is not located on the

same level with the level of two

Forms.
Single rotor impact crusher has the following three.
(A) without leveling sieve Crusher (Crusher)

(2) with leveling sieve Crusher (Crusher). Such models can control product particle size, and thus fewer particles too large, narrow particle size distribution, particle size is

uniform. This is because grading and leveling sieve plays the role of broken too large particles.
(3) reversible single rotor Crusher (Crusher). Rotor can reverse, forward rotation, inlet disposed in the body just above the two symmetrically arranged in the crushing cavity

back plate, double rotor crusher has the following three.
a. Two co-rotating double rotor rotor crusher. Equivalent to two half-rotor impact crusher used in tandem, large crushing ratio, uniform particle size, large capacity, but the

power consumption is higher. At the same time as the coarse, medium and fine crushing machinery used. This crusher can reduce the broken plate

Number, streamline production processes.
b. Two rotors counter-rotating double rotor crusher. The equivalent of two single rotor impact crusher used in parallel, production capacity, larger pieces of material can be

broken, as a large coarse, medium crusher used.
 c. Two rotors counter-rotating double rotor crusher. The main use of two materials thrown when the rotor relative to smash hit autocorrelation, so crushing ratio, metal wear

less.
