Secondary Crusher Benefits

The difficulties of broken clay, almost breaking it off in the secondary. Breaking and crushing coarse clay, although there are some difficulties, but has basically been resolved.Users want to shreds breaking is: a broken discharge is less than 65mm, less than two broken 15mm, yield ~ 45t / h, sodium handling, but in the country has not broken to find a suitable model.

Primary crushing roller breaking space instead of increasing the secondary crusher, but the wear is too severe, the finished product size, production can not meet the requirements. Moreover, since the crushing ratio is too large (65/1.6), must be set at least two broken, so that each of the wear and tear caused by severe and greatly increased power consumption. Increase in power consumption did not increase grain size and yield of qualified products, but increased consumption of wear and tear.

Therefore, both from an economic point of view, or from the configuration of rationality, efficiency of resource use, said a pressing need to increase the appropriate secondary clay crusher. The main secondary crushers are impact crusher (Hydraulic impact crusher, PE series impact crusher), cone crusher (Short head cone crusher, Hydraulic cone crusher, Spring cone crusher) and Vertical Shaft impact crusher.



Secondary Crusher To Clay

Clay Secondary Crusher has a wide range of uses, the hardness is not high, but the clay processing, especially in deep processing, fine processing is more complex. As the clay sub-crystalline and amorphous material, water layer, generally 15 to 28% moisture content, a larger viscosity, specific gravity heap 0.8 ~ 1t/m3, thus breaking them become more difficult.

Some professional institutes, design and development of the 2PGC1250x1250, 2PGC1400x1400 Double Roll broken clay to solve the cement industry, the material requirements of 35 ~ 70mm in size, but it can not meet the requirements of crushing process.


The Difficulty Of Crushing Clay:

1, By extrusion, the water precipitated on the surface of soil mixed with goo, attached to the broken wall, resulting in stuffy car. Only so quickly through the compression layer of clay, and set the scraper so that it can not stick in the wall to achieve an effective break. Clearly, the jaw crusher, cone crusher, hammer crusher, vertical shaft impact crusher in the form of models do not have such conditions.

2, Because of clay and shale, sandstone, granite, basalt, diorite, etc. associated with, a certain amount of ore mixed with stones, because of the internal water, in winter -20 ~ -30 ℃ in the north, the temperatures will be frozen hard The earth, the clay crusher design must consider wear and strength.

3, Roll crusher is only suitable for crushing clay models. However, in order not stuffy car, much better roller speed, and when speed increases, the roller wear is significantly increased. Therefore, the nausea in the design of cars and wear a pair of difficult to reconcile the contradictions.



Clay Instruction

Clay mineral is water containing feldspar crust and rocks after long-term weathering and geological generated in the various types of sediments and rocks in common. Are: kaolinite, montmorillonite, illite (clay mica), vermiculite, chlorite, talc, serpentine, pearls, clay and so on. Ore due to the different iron content, showing white, green, green, blue, brown, pink and other colors, can be described as colorful.

Clay sub-crystalline and amorphous material, water layer, the physical nature of performance: more than water, generally 15 to 28%, a greater viscosity, the proportion of the heap in the 0.8 ~ 1t/m3.

The use of clay minerals are many, such as montmorillonite has a strong adsorption, can be used for metal casting sand mold binder; can be made of heat, water, acid and the Al-Si thin film; can be used for promoting long-term fertilizer fertilizer agent; clay mineral products in the cement industry as a binder; in medicine can be used for external application of thinner, fungicides; in civil engineering can be used for dams, underground waterproofing agent; in the ceramic industry can be pottery, refractories, enamel; in the textile industry can be used to increase the durability of fiber; also can be used as water softeners, bleaching agents and so on.
