ball mill wear for ball mill

Modelling and simulation of ball mill wear ScienceDirect

1993-2-1  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. 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

Grinding Media Wear Rate Calculation in Ball Mill

2017-4-29  In any mill, the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball.
