Consumption of steel grinding media in mills – A review ...

2013-8-1 · Pintaude et al. (2001) have considered the effect of particle size on the abrasive wear of high-chromium white cast iron mill balls. They have concluded that the ratio of steel ball to particle size is the critical factor. The highest ball wear rates occurred during grinding of fine granite under dry (120 mg/cycle) and wet (129 mg/cycle) conditions

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.
