A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
