Contact网页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.
Contact网页2007年4月1日Introduction. As coarse grained, easily processed ore bodies are depleted, more disseminated, fine-grained ores are being treated. Adequate liberation of valuable components within a fine-grained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cut-off of 45. μm..
