Modelling and simulation of ball mill wear - ScienceDirect

In the mineral processing industry, ball mills are used to reduce ore from one size distribution to another. Ball mill wear occurs as a result of the violent interactions within the ball charge. In the present article, a mathematical description of wear has been added to a ball charge motion model.
