Mills grind the particles using the mill or milling media and can quickly produce fine powders from coarse grains. Mills are commonly used in the mining industry. In cutter mill, size reduction occurs by fracture of particles between the two sets of knives. In hammer mill, size reduction occurs by impact, by four hammers attaching on a central ...

Motor power and media addition. The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.
