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.

In normal operation, the charge starts sliding after the mill reaches a certain angle of between 40° and 70° and the load torque decreases. This decrease in torque is monitored and used by our "Frozen Charge Protection" to stop the mill before a dropping frozen charge damages the mill. After stopping the mill, the charge keeps in "frozen" condition and must then be broken up with ...

Ball Mill Charging System

Mill ball charging systems have undergone little change during the past two decades. Most operations utilize a locomotive/ball car combination to load and haul charges from the ball storage bin to the mill charging boxes or, alternatively, transport charges to the charging boxes by means of a ball bucket handled by bridge crane. The grinding section at Island Copper is a semi-autogenous, two ...
