The smallest ball size typically charged into ball mills and tower mills is ½ inch (12.5 mm), although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al .,[ 7 ] a GIS mill charged with 5-mm steel shot, and with other operating conditions similarly optimized, achieved high energy ...

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.

Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
