2009-8-26  mill liner profiles Valderrama et al. (1996) performed tests of measurement of the wear of lifters in a laboratory ball mill. The object of those tests was to study the role of cascading and cataracting motion of balls on the wear of liners. They used a mill having a diameter of 0.28 m and a length of 0.11 m. The mill was

Predicting charge motion, power draw, segregation and

Segregation is an important issue in rotating mills. Size segregation of steel balls and size separation of small rocks from the larger bails are examined. Predictions of liner wear rates and distributions are made. Evolution of the liner profile can be modelled in order to predict the lifter life cycle and its effect on the mill operation.
