In this context, the term average size depends on the method of measurement. In the industry, screening or sieving is widely used to evaluate particle size distribution in granular materials and powders. In case of coarse crushing the size reduction ratios is below 8:1 and in fine grinding it is more than 100:1.
1) Continuous grinding-classification circuit. The crushed ore is ground to the product particle size required by the subsequent production process. It is mainly applicable to the treatment of ore with uniform and fine embedded particle size. For example, the concentrator adopts the continuous grinding-classification circuit of one-stage rod ...
