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.

Grinding • Classified in to two • Plain grinding – Milled to a free flowing meal consisting of sufficiently uniform particle size • Selective grinding – Grinding operation is carried out in various stages depending upon the differences in structural and mechanical properties of components of grain .
