An analysis of the influence of grinding aids on the breakage process of calcite in media mills

摘要

The effectiveness of calcium stearate, boric acid, and silica as additives for the fine grinding of calcite in media mills, i.e. ball, rod, and vibration mills, were explored, by following teh size distribution of the ground product collected at various time intervals from 15 s of grinding up to 30 min, using a single size feed.
