Medium Characteristics on Selective Grinding of Low Grade

Selective grinding of bauxite with ratio of Al2O3/SiO2(A/S) 4.4 at ball mill were studied in order to investigate the effect of grinding media characteristics on selective grinding of bauxite. Results show that when diameter of ball media is Φ15mm, selective grinding effect is best and at this moment A/S of the product at -0.5+0.28mm granularity is up to 7.5.

Eight tips for effective grinding The Fabricator

The act of grinding can be deceivingly simple. But the devil’s in the details. Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the “cutting tool” of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool.
