In this paper, COMSIM, a new simulator which runs under Excel spreadsheet will be introduced which uses a Population Balance Model (PBM) to simulate ball mills. Plitt and Nageswararao models have been used to describe the performance of hydrocyclones, which by linking to the ball mill model allow for closed-circuit simulations.

Simulation of Size Reduction in Ball Mills and DEM. ... Another reason for the early success of DEM in tumbling mill simulation lies in the fact that the most common grinding media are balls, typically made of steel and other ferrous alloys. ... In the case of ball mills, this is certainly not straightforward.
