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.More

These extremely low energy efficiency values might be the result of the extended ball milling time used for pretreatment. Energy requirements for other types of mills have been thoroughly discussed elsewhere [111, 112, 114] and the comparisons strongly supported the higher energy consumption of the ball mill relative to other mill types.

Ball Mill Specifications All-Steel Shells and Heads. Ball-Rod Mills have heavy rolled steel plate shells which are arc welded inside and outside to the steel heads or to rolled steel flanges, depending upon the type of mill. The double welding not only gives increased structural strength, but eliminates any possibility of leakage.
