Modelling and simulation of ball mill wear

In the present article, a mathematical description of wear has been added to a ball charge motion model. Wear is associated with the comminution mechanisms found in the ball charge profile. It is assumed that ball mill wear occurs in each of three comminution zones, with adhesive wear found in the crushing and tumbling zones and abrasive wear arising in the grinding zone.
