Ball milling as an important pretreatment technique in ...
The grinding balls tumble randomly throughout the whole tank volume and attain irregular movement. As a result, both shear and frictional forces are generated dominantly. Impact forces are also induced by the constant collision between balls, between balls and the container wall, and between balls and the impellers.

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.
