The condition of the discharge grates clearly has a profound influence on the total ball consumption.According to our theory we predict that with new discharge grates fitted the ball consumption of the mill should decrease to I~New graoos Reference to Table II shows that during periods 13 to 15 a total mass of 54 401 t of ore …
22 May, 2019 The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground …
