Crushing machinery enterprises to enhance the capability of independent innovation

China is the mechanical manufacturing country , but not power. Chinese production has accounted for a large proportion of broken machinery of global construction machinery

production, but compared to some crushing and screening plant high-end equipment with the international advanced enterprise products, there is still a wide gap . Then, " Made in China" broken machinery

The status quo is what it?

According to the status quo stone feeding machine of China's discovery : China to create a " big but not strong Chinese crusher crusher manufacturer has been shouting for years ." To build a world -

class brand "slogan , the status quo is not satisfactory , the crux of what ?

"Made in China " can be broken machinery products sold overseas in recent years , has indicated that the quality of Chinese machinery products has been recognized by the world.

The data show that China's crushing machinery sales and sales have leapt to the forefront of the world , is expected in 2012 China crusher

Industry sales and sales growth will be above 20% , with exports expected to reach nearly ten billion U.S. dollars .

Although there are risks in overseas M & A process , but Chinese enterprises " going out" is inevitable. In addition, through cooperation with foreign companies , China 's

position in the world has improved.

China Machinery Industry Association crushing official said , China crushing machinery enterprises to enhance the ability of independent innovation. The central government

introduced a lot of " Twelfth Five-Year Plan" and the broken machinery industry relevant if these plans can be implemented , will promote China crushing machinery enterprises

upgrading.

In addition, the development of bad business mainly because of broken machinery hydraulic system and engine problems , because these components require companies in terms of

precision casting and machining has a very strong ability . Of course , this also with the overall level of national basic industries associated with it. A

Hydraulic valve includes more than 400 parts , the United States , Japan and other countries can be assembled in the country is good, but we can only rely on imports .

Currently, developing countries called the "three basic industries" ( mechanical foundation , basic manufacturing processes and basic materials industries ) , if these policies

can be implemented , China's basic industries will be able to enter a new stage , China's crushing machinery products with foreign countries the gap between the products on

Will become increasingly smaller .

Water contained in the material of the vibration sieve effect

 Shaker at screening material , the moisture contained in the efficiency of the screening effect of the large water containing not more than 7% of cases , screening can be

normal, when the moisture content greater than 7 %, the material is easy to form a group, screening effect .

Moisture contained in the material Vibrating feeder can be divided into two kinds : one is inherent moisture present in the pores of the material ; rather external moisture , the material

attached on the surface of the water, such as mineral mud during the rainy season , underground rock fissure water , groundwater and transport shaft fissure water , dust removal

equipment spray screen machinery water , fog rainwater leaching when stacked . External moisture content and the material is proportional to the surface area . Fine material as large specific

surface area , fine with external moisture high. Inherent moisture has no effect on the screening process , the external water on the screening process a greater impact. High

clay content of clay minerals that contain many large adhesion material , even water is very low, but also easy to make the material bonded into a group , clogged sieve sieve

sieve feeding mouth and clogging .

In choosing a shaker device is to be given to those

Customers choose shaker device is what should be considered :
    Shaker customers ready to buy the equipment when not quite understand how to choose the client device , the following details about . Select vibrating screen equipment in

general to consider a space-saving apron feeder drive power to be small. At the same time to be able to guarantee rotation and pulsation amplitude of movement to be small, vibration

frequency

Rate should reach three thousand times per minute , or a combination of centrifugal force and amplitude -frequency vibration and other factors are likely to affect the normal

operation of any shaker . In addition , sand vibrating screen the need to have a correct combination of the direction of slope and rotation mechanism, which is essential for display . Typically

, Shaker requires a large opening , large amplitude display. If too little investment , then the material may be wedge-shaped openings , etc. , or clogs . Increase investment in

the future , need to know how to prevent clogging because blockage is unnecessary and will increase the daily wear and bearing

And lower screening efficiency. Material per unit time to be increased rate curve through the entire screen, so there material at a faster rate while the lathe by a thin high

efficiency needed for screening. When the material too fast and cause the material to ribbons by the breakdown when the material reaches

Screen appears when opening the cloth maximum tilt angle . At this time a large number of high-quality material through the screen too quickly , resulting in poor efficiency .

When an existing screen fails, if the screen structure is also suitable for new applications , then should be timely checked and consultation

Ask vendors to see if there is a need to modify the place . Operators can also pass the following information provided by suppliers to get a good shaker, the highest tons per

hour through the filter , including any cyclic loading or any sudden increase in feed rate . Particle through a complete

Analysis or analysis of the material for screening , if conditions allow , the best estimate analysis method used . The type of material and the weight of the probability of

failure per cubic meter . Each sieve expected fracture. Material carried by the surface of the water filter , if it is required to damp

To add a certain amount of water or of dried material . Special operating requirements or conditions , such as temperature, wear, corrosion or with other physical properties of

materials, efficiency and product requirements, determine filter surface or installation problems because it will directly affect the screen size

Inch screen real choices, and the ability to use . General Type: vibrating screen can be divided into two categories : one for mechanical vibratory shaker, the other for power

by the vibrating shaker .

Production quality control during the operation of natural gravel Nongling hydropower production run quality control process is to ensure that the quality of a key link in the

aggregate, such as the full feed, filled with crushing, crushing rate increase, discharging granularity control equipment to minimize once broken to become a

The proportion of material goods, broken, crushed finely segment selection, control every stage crushing crushing ratio, to avoid the re-formation of flakiness stone; adjust

aggregate ratio control level within the ultra-Hudson Trail aggregate content, control of natural fine sand degree modulus and dust content, clay content and other control

aggregate. These

Quality problems, in addition to strict production rules, it must also take all the necessary technical means and technological measures to ensure the quality aggregates and

ultimately ensure the quality of concrete.

(A) control equipment nesting size. Equipment nesting size control of the main objectives: first, to make the rational allocation of broken machinery running, the second is to

reduce aggregate flakiness finished proportion Third, adjust the finished aggregate proportion of each grain. If crusher GP100SC through technological innovation

After removing the internal feed wheel, the maximum increase in grain size is 40mm, the corresponding primary two sets PE400 × 600 jaw crusher discharge port width is adjusted

to 40 ~ 60mm. Thus, after primary crushing particle size greater than 60mm product was significantly decreased by two sieve again broken into 40 ~

20mm diameter products increased significantly, again broken product is less than 20mm, after several adjustments crusher discharge port width can adjust the product in the

proportion of fine aggregate. In the above process can achieve the same reduction aggregates flakiness content purposes.

(2) control aggregate mud content. Stone, clay content is produced by conventional indicators. Wool production in clay content to take control of the main measures are: wool

mining area covering stripped clean to ensure that mining wool to meet the quality standards and regulatory requirements; secondly according stockyard exploitation Fan

Wai and reclaimer standards, excavation sequence by side edges wool stripped overburden excavation, excavation slope ratio of 1:2 slope comprehensive excavation, excavation

average thickness calculated by 4m, including comprehensive consideration of 0.5m above water underwater part is 3.5m. controlling aggregate mud content main measures are:

First, to ensure wool exploitation rate; Second excavation process required to hand on the face appearing in oversized stone, mud, debris and other timely treatment to reduce

the production system in the production process due to oversized stone, mud, debris clogging and other contamination of the finished product; third is in the 1st tape machine

arrange for ultra-

Diameter stone, mud, debris processing, the use of aggregate screening when flush screen surface on each additional high-pressure hose, rinse the remaining soil to reduce the

amount of refined clay aggregates.

(3) within the control of the particle size grade oversized aggregate content. Adjust the size of oversized aggregate content within level process measures are as follows:

Firstly, crushing levels of feeding, nesting width adjustment crushing ratio, by adjusting the particle size of more than 40mm crushed aggregate excess broken into small

aggregates, the use of belts

Machine Part 20 ~ 40mm transhipment will broken again in the aggregate shaping; 10% of the enlarged screen mesh, ensuring screening, sieving rate increase under the premise of

conscious oversized content to supplement aggregate crushing caused by high drop Johnson Trail . These processes regulate the source material in Nongling change and each station

using a single material

Position on the various grading finished aggregate demand changes, the aggregate production for 20 ~ 5mm in proportion to the new request to get a better application. In

addition, to strengthen quality control of daily work, regular intermediate products and final products of each particle size curve analysis, according to the conclusions of

timely investigation

Related processes.

Conclusion Nongling natural gravel hydropower production system during operation through strict quality control and inspection, so that the aggregate production of various

technical indicators meet the requirements, the quality of concrete pouring for the dam to provide a guarantee, but also for similar system construction provides

Can learn from the experience.
