May 15, 2014 For efficient use of energy in grinding 1.ore particles should form a coating on the liners and the grinding media. 2.the pulp should be fluid enough for steady flow through the mill. Thin pulp - Solids settle, centrifuging occurs, coating on the grinding media is not possible- improper grinding .

Flotation The Past Present And Future Of Mineral Processing

With CPF, you can usually take that up to 400 microns, which reduces the amount of grinding needed by half. In grinding, the amount of energy required increases disproportionately as the material becomes finer the finer the material being ground, the more energy is required which is why ultra-fine grinding mills use a lot of energy.
