400 37 What does mesh size mean? It is the number of openings in one inch of screen. A 4mesh screen means there are four squares across one linear inch of screen. A 100mesh has 100 openings, and so on. As the mesh size increases, the particle size decreases for finer material. Mesh size is not a precise measurement of particle size.

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.
