Fine Grinding Technology for Mines and Concentrating

Conventional ball mills rotate the mill body (a horizontal cylinder), tumbling both rock and metallic balls. Stirred mills use an internal auger to agitate the feedstock (ore which is fed into the mill as a slurry) and grinding media (sand, ceramic balls), which produces finer, more uniform grind sizes with reduced energy consumption.

Cement mill Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
