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.

VeRoLiberator - High Velocity Rotation How it works

What happens inside the machine? The VeRoLiberator ® has the potential to replace ball mills and SAG mills, which are robust but also known for their breakage inefficiency and very high energy consumption. A comparison between the breakage principle of ball and SAG mills and the VeRoLiberator ® is therefore only logical. This mechanism is also shown as part of the VeRoLiberator ® Video.
