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.

1. Introduction. The efficiency of most grinding processes which are performed wet or dry is very low. Dry grinding, in particular, is a difficult process in terms of material transportation since the particles are prone to form agglomerates and coating on the media and mill liners due to the static forces that occur during the grinding operation [1].

Ball mills have been used as the main grinding equipment for finished cement production for over 100 years. Although simple to operate and costcompetitive relative to other technologies, the low efficiency of ball milling is one of the main reasons for the development of more efficient grinding processes in recent years.
