Effect of grinding aids on the kinetics of fine grinding energy .The effect of grinding aids on the comminution coefficient, K, was also investigated. It was demonstrated that the grinding rate for calcite could be improved by the addition of grinding aids. When using grinding aids, K improved by 16.0% and 34.2% for 60 wt% and 70 wt% slurry concentrations, respectively. Thus grinding.fine grinding of calcite,Calcium Carbonate Grinding Mill_Calcium Carbonate Mill_Calcium .After being screened to remove gangue, raw materials will be delivered into stone crusher for coarse crushing, then to grinding mill for fine grinding to get micro calcium carbonate powder., finish through classifier for grading.

Influence of grinding on the structure and colour properties of talc .

Abstract. The influence of grinding on colour and particle-size properties of talc and smectite from a white bentonite were studied and compared with a fine-grained calcite from a chalk. Grinding decreased the grain size of all three minerals. The crystallite size and structure of smectite was not affected but the crystallite size.
