How to choose proper grinding media for your ball mill
Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 120mm according to different grinding requirements. In a cement ball mill, generally, φ50–100mm steel balls are used in the coarse grinding chamber, φ20–50mm steel balls are used in the fine grinding chamber. 2.

GSI.cc > Ball Mills
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.

Ball milling
Ball mills are slow compared to other methods of grinding, it could take hours, for example, to grind all the particles in a clay to minus 200 mesh. Industrial mills seeking nano-sizes might run 24 hours or more! ... Commercial ceramic grade powder is minus 325 mesh, the companies doing this obviously have very good grinding equipment.
