reduction materials for ball mills

Ball mills arefilled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

Material is reduced insize by impact as it passes through the rows of pins. A bottom outlet is used when material is gravity discharged from the mill or a tangential outlet is used when material is air conveyed away from the mill. No screens are used in pin mills to control particle top size.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to afine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by both impact and abrasion.

Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut 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.
