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.

Keywords: Energy balance, Modelling, Simulation, Mixing, Grinding mill, Mill power, Mill temperature I. Introduction Effective mill control is believed to be a key element in the drive towards lower energy and material costs in grinding circuits but such a control system would require good understanding of the dynamic behaviour of mills when the operating variables are changed and the ...

01-09-1992 The Population Balance Model, PBM, contains flaws making its use for effective simulation and control of milling circuits questionable. Presented is an analysis, based on published experimental wet grinding data, showing that the assumption of linearity, used in solving the PBM, is certainly wrong in many grinding mills and wrong for most commercial wet grinding circuits.

Conclusions A dynamic energy-mass-size balance model has been developed that can be utilized for dynamic simulation of a wet open circuit grinding mill. This model may serve as predictive tools for providing insights of the process and thus it would lay a ground on which sound control schemes can be created for improved mill product quality and process performance.
