Vibration isolation capability round griddle and screening efficiency

Circular vibrating griddle ( round vibrating screen ) due to vibration griddle only one axis , also known as single-axis vibration griddle . Circular vibrating griddle ( round

vibrating screen ) screen box China Vibrating Screen trajectory is circular or oval named.

    Circular vibrating griddle ( round vibrating screen ) when activated and deactivated , since the amplitude of the resonance region , the screening machine speed will

increase , vibrating screen manufacturers causing severe overload spring to shortened life expectancy , belts easily damaged , and it will affect plant construction safety. Dongyuan round vibrating machinery

production

Shaped vibrating griddle increased vibration absorption device , and eliminate vibration device is used to eliminate this resonance phenomenon , to ensure safe mining operations

. When increasing the rotational speed of the vibrator to about twice the critical speed , the eccentric block pop work required to produce the vibration force and amplitude.

When parking , vibration

When the resonant actuator speed to about twice the speed , pull back the spring eccentric vibrator basically in flat horizontal position , does not produce exciting force ,

will not increase the amplitude of the screen box , to eliminate vibration purposes.

    Circular vibrating griddle ( round vibrating screen ) is divided into ordinary circular vibrating griddle ( round vibrating screen ) , and self-centering vibration griddle ,

the difference between them lies in the different structure of the vibrator , the former center of the pulley bearing center and located in the same a straight line , when the

vibration griddle operation , pulley will immediately sieve

Boxes together vibration, thus causing repeated stretching of the belt is leaving easily damaged and requires a smaller amplitude. Because of these drawbacks, this shaker has

been rarely used in the production process .

    Self-centering vibration griddle center is located between the center pulley and the center of the eccentric bearing , and to the center line of the eccentric pulley and the

center of mass of the vibration body synthesis , therefore , when the vibration of work griddle pulley do not shake along with the screen box , making rotary motion from

And also with a larger amplitude in order to improve screening efficiency. Thus , self-centering vibration griddle developed rapidly, to get a wide range of applications . Mine

production is currently used in circular vibrating griddle ( round vibrating screen ) generally are self -centering vibration griddle this type.

How to choose the griddle screen

        Air screen host , motors and fans inspected once a year , the amount of added oil, remove dust inside the motor .

        With a sieve shaker shaker machine must be repaired once or twice a year , each time you want to add oil maintenance , connecting bolts to tighten .

        Replace the airflow mesh sieve to ensure uniform tension , fixed at both ends of the rope , you need to adjust the screen edge fastening edge .

        Second, common faults and troubleshooting

        1, when the capacity is mainly the application of screening tests to detect the material meets the screening requirements.

        2, when the volume suddenly increases taken when handling product testing analysis, if unqualified finished , check the screen is intact.

        3 , when the material suddenly not working .

        ( 1 ) should check whether the fan is normal, if the fan flow reduction, should examine discipline .

        ( 2) Check whether the discharge auger does not rotate , you can not discharge .

        Third, pay attention to matters

        1, the machine should not be screened with a viscosity, water content greater than 5 % of the materials and flammable and explosive materials.

        2 , the same type of air screening machine, the greater the corresponding mesh screening material yield.

How reliable vibration motor mounting

     Vibration motor ( mounted on the motor shaft at both ends eccentric block , using its high-speed rotation generates centrifugal force ) because of its compact structure

, easy installation , no transmission vibrating screen manufacturers components , and can be part of the vibration and many other advantages , more and more applications in various industries extensive. The

general structure of the vibration motor shown in Figure 1 ,

That allogeneic seat shell with shell seat one. Shell seat variant ( Fig. 1a) , respectively foot supporting surface fused with two end caps , and its manufacture is more

convenient , there are still many manufacturers vibrating screen supplier use , but its drawback is two bottom foot is processed twice . Since the existence of assembly errors , and some foot

Surface can not be guaranteed in a unified horizontal plane , so that the vibration motor work, a few foot bolts of the force will be uneven. The vibration motor excitation

force almost all these bolts passing through , so that a larger force on the bolt is easy to damage , in turn cause other spiro

Bolt damage burning motor . And Fig 1b, one of the seat shell of the vibration motor because all of the foot on the housing bottom , easy processing time , thus ensures that the

bottom level of the foot , eliminating the above-mentioned problems, the vibration motor life can be guaranteed .

Horizontal vibration motor excitation force adjustment

Centrifugal force vibration motors are factory adjusted to 80% , need to sea when ( export ) Centrifugal force adjusted to 0% . Use the following steps to adjust :
⑴, relax protective cover screws and Screening machine remove the shield at both ends ;

⑵, exciting force is less than MV50-2, MV50-4, MV50-6, MV30-8 vibration motor ( not included four specifications ) , the outer eccentric block is adjustable , surface marked

with the largest percentage of the exciting force ruler , inner eccentric block is a fixed block , use the fastening bolts are pressed on the motor shaft. Both end surfaces of

the shaft engraved baseline. Loosen dewatering screen the sides of the outer eccentric bolts on both sides of the outer eccentric rotation in the same direction , so that the shaft aligned with

engraved lines on the outer eccentric ruler engraved lines excitation force , to the required excitation force , tighten the eccentric block bolts , fitted with protective cover

;

⑶ exciting force is greater than or equal to MV50-2, MV50-4, MV50-6, MV30-8 vibration motor ( including the four specifications ) , the eccentric block is a fixed block , keyed

to the shaft , can not rotate. Adjustable eccentric block within the block , with the outer surface marked with the largest percentage of the ruler exciting force , the use of

fastening bolts pressed on the motor shaft . Loosen the sides of the inner eccentric bolts on both sides of the inner eccentric rotation in the same direction , so that the

inner eccentric excitation force on the outer eccentric ruler engraved lines aligned slit on the block , to the required excitation force , tighten the eccentric bolts , fitted

with protective cover ;

Note: Except for special applications , the vibration of the motor shaft at both ends eccentric position must correspond to both ends of the eccentric set percentage must be

equal , otherwise the vibration motor generates a huge mistake to centrifugal force , the vibration of the motor mechanical damage .

Cause weighfeeder factors of error

     Governor weighfeeder by the scale body and a controller , the controller accepts the scene scale body load pressure sensor signal and speed sensor speed signal processing,

in actual use , the Crusher machine speed signal can generally reflect the actual scale body speed , low failure rate .

Therefore, the feeder , the measurement accuracy depends on the scale body load signal accuracy . Silo material level , the belt is running friction material humidity,

temperature and belt tension have directly or indirectly affect the size and direction of the belt Mobile crushing plant tension variations , resulting in the actual load

Away from the calibration load , directly affecting feeder metering accuracy .
    More varieties of feed ingredients in the case that the number of over 12 silos , even when adjusted feeder model , speed, it is difficult to control in 6min completed

within the ingredients, so to consider configure two batching scales . Two scales simultaneously ingredients, aniseed into a large scale, small material into the small

Scale, not only can greatly shorten the batching time , but also improve batching accuracy , help to improve feed quality and yield , reduce energy consumption. Weighfeeder

ensure accurate dosing , batching shorten the time .

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.
