The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the mass …

In order to reduce it, greater than normal velocity must be applied. When the speed exceeds 250 fps (75 mps) the result is high inter-particle compression and forceful attrition which achieves a milling effect. REMco Vertical Shaft Grinder - VSG units operate well above crushing speeds and mill with velocities up to 360 fps (110 mps).

The RMS analysis was estimated for the initial and later stages of the grinding. The mill noise emission was observed to be affected by the different ratios of the two rock types in the feed. At the initial stage of the grinding, 75 % model quartz and 25 % iron ore emitted the highest mill noise and were reduced with an equal blend ratio.
