Introduction :Mar 25, 2007 If the ball mill will always operate at a fixed speed, the VSD is an expensive option. One major disadvantage of using a VSD or a fuid coupling, is that there is an additional 5% loss all the time that the ball mill is operating. The soft starter has only about 0.5% loss and a

Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital cost. However, the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media.
