Roller crusher has the advantages of simple structure, compactness and lightness, reliable work, low price, convenient maintenance, etc., and the crushed product has uniform particle size, small over crushing, and fine product size (can be crushed to less than 3 mm). Therefore, it is suitable for small-scale concentrators for processing brittle materials and clay-containing viscous materials for medium and fine crushing.

Increase the surface area of ​​the material: The surface area of ​​the material is increased after crushing, which can improve the physical effect and chemical reaction speed. After the cement clinker is fired, the reaction speed is related to the degree of material fragmentation. The more broken the material is, the faster the reaction speed proceeds, and the corresponding combustion speed is faster, which saves part of the fuel.

 

Production of concrete aggregates and artificial sand: The production of concrete requires aggregates of different sizes. The large stones mined are crushed and screened into gravel of different sizes. The crushing method can also be used to prepare artificial sand.

              

 

Separation of useful components in the ore: crushing and grinding operations in the beneficiation operation can remove the useless impurities in the minerals, thereby obtaining useful concentrates.

 

Subsequent raw material processing: In coking plants, sintering plants, agglomeration plants, building materials, and powder metallurgy departments, the raw materials used are generally large in size, which requires crushing to a specified size for subsequent processing. In the food, chemical, fertilizer, pesticide and other sectors, the product is often broken into powder for use.

 

According to different customer needs, Shanghai Zhuoya divides the roller crusher into double-roller crusher, double-roller crusher and double-toothed roller crusher for different enterprises.
