The nonchaining spreadsheets can be caught in a circular reference where a step change proceeds around the circular reference from cell to cell without dampeningout. An example would be a closedcircuit ballmill feed calculation cell that contains the value 100 on the first iteration, 0 on the second, then back to 100 again repeating the cycle.

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 closedcircuit simulations. To describe
