A. Increase material specific surface area. The material specific surface area is increased after crushing so as to enhance the physical effect and chemical reaction speed. For example, when several different solid materials are mixed, the finer the materials are crushed, the higher the mixing uniformity.
B. Preparation for concrete aggregate and artificial sand. It is to crush large block of aggregates into various kinds of rubble with different compressive strength. Under the condition of lack of natural sandstone, we normally use crushing method to produce artificial sand. The sand making machine manufactured by Luoyang Dahua is far ahead of the market.
C. Dissociation the useful component from the ore. In the process of beneficiation, crushing and grinding is to separate the useful component and impurity that closely combined and commensalism from mineral, namely Dissociation. After dissociate, we can get pure high grade mine by removing impurity.
D. Preparation for next processing or easy to use. In the coking plant, sintering plant, briquetting plant, building materials and powder metallurgy department, the size of raw materials are large, which need to be grinded into the required size for further processing usage.
