The Ratio Of Grinding Media Balls

During the operation of the mill, a certain number of steel balls need to be added regularly to complete the grinding operation. Because the grain size of the raw ore into the mill is composed of several grain grades, it is not possible to add steel balls of one size, but to separate out several grain grades of steel balls of various corresponding sizes in the raw ore to complete the operation. The best efficiency. In actual grinding operations, the size of the steel ball is too large, which will cause excessive impact force, which is prone to "penetration crushing" and over-crushing; the small size of the steel ball will result in insufficient impact force, and the grinding products will be too coarse and ground. Not detailed and other issues. Therefore, in production and operation, it is necessary to adjust the most suitable steel ball supplement plan in time according to the nature of the original ore and the level of particle size composition. Anning Mining of Yunnan Phosphate Group has proposed to change the steel ball supplement plan, under the premise of ensuring the degree of dissociation of the grinding products in the monomer, effectively reducing the amount of overgrinding of the grinding products, and greatly improving the grinding efficiency and production capacity.
