Method How to Reduce Ball Mill Wear by Cathodic Protection

The present work was undertaken to develop a method to cathodically protect a ball mill to reduce materials loss from mill liners. The essential science of “Cathodic Protection” is to apply a sufficiently negative potential to a metal in a corrosive environment such that the anodic corrosion rate is reduced to a negligibly small or acceptable value.

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.
