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. The ...

Ball Mills and Ball Charging Bulk Handling Technologies ...

During the grinding process, grinding balls are consumed due to abrasive wear and must be replaced progressively (and ideally continuously) to maintain the optimum 'charge' within the mill. Safe and reliable feeding and delivery of new grinding balls to the mill is a key concern for many mine sites. Manual handling is a hazardous task and should be avoided where possible to reduce the risk of ...
