Mine Process Theory Grinding Milling Ball Mill

Several basic assumptions are made in modeling of the grinding process in various types of mills and milling circuits Most frequently it is assumed that the mill's content is uniform and thoroughly mixed by the rotation of the mill and the movement of the grinding media [44] In this case the model is known as a perfectly mixed model.
