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. At a certain height, it will automatically ...

The theoretical power draw model of a mill or Morrell's power model is an elegant solution to mill power modelling. It has the merit of treating autogenous, semiautogenous, and ball mills as one single class of devices for which the power draw could be predicted with the same equations. The model, initially intended for
