Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

GSI's ball mills are housed with oversized roller bearings and a complete drive system discharging mesh sizes from ~40M to <200M. The capacity, or throughput, of our GSI ball mills are directly linked to the particle size of the ball mill discharge. For instance, it is roughly 3 times as fast to reach a 65 mesh grind than a 200 mesh grind.
