Majority of traditional mill simulation models have been successfully applied in mill
circuit design and optimization. However, only limited success has been reported with respect to
dynamic mill control. This is partly attributable to the fact that these models are based on steady
state analysis and fail to account for energy balance inside the mill. In this paper, an integrated
model has been developed based on energy-mass-size balance for dynamic simulation of open
circuit wet grinding mills under MATLAB environment. The model combines information from
energy-mass balance, material breakage mechanisms, fundamental material properties and the
milling conditions in a simple and clear representation of the physics and thermodynamics of the
wet milling process, thereby addressing the limitations of traditional model formulations.
Simulation test results depicting the dynamic response of the model are presented in Part II.
Successful validation of this modelling approach would go alongside improving the current
methods of continuous control of grinding mills |
