key factors affecting mill throughput and grinding efficiency: mill speed, ball loading, and liner lifter face angle (angle between the lifter face in contact with a grinding ball and the lifter base). Its central hypothesis is that face angle drives a ball mill's grinding efficiency and throughput independently of the type of liner used.

The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

A vibrating screen was used to provide a mill discharge product separation at 19 mm (¾ in.). The minus 76 trail (-3 in.) plus 19 mm (+¾ in.) screen oversize product, which are the "pebbles", were then crushed to essentially minus 19 mm (-¾ in.) in a crushing circuit. This product was returned to the feed end of the mill.
