Predictive Model for Ball Mill Wear Canadian

Predictive Model For Ball Mill Wear Canadian

Jul 18, 2013 Ball mills, characteristic of the mineral processing industry, are used to reduce ore from one size distribution to another. Wear is associated with comminution mechanisms found in the ball charge which in turn affects grinding performance. In this work, ball mill wear, as a function of mill operating variables, is determined using a mathematical wear model.
