Power required to drive a ball mill with a particular ball load is proportional to where, D diameter of ball mill 1 1D
Apr 01, 1999 The calculated power draft is maximum at about 50 ball load. According to Eq. 1, mill power is a function of ball mass M b and the distance between mill center and the center of gravity of ball mass r g. So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum.
It is commonly said that it is hard to perform energy saving reconstruction to the Chinaware ball mill. However, this machine always contributes at least 80 of the factorys total power consumption. To respond to the governments appeal, Gozuk launched a new series variable frequency drive - that can be used in the Chinaware ball mill.
