A simple dynamic model combining energy balance and population balance has been
utilized to assess the dynamic response of the mill to changes in mill operational parameters for
purpose of establishing a predictive control tool. The manipulated parameters are feed rate, feed %
solids and ore hardness index while the response variables are mill power draw, mill temperature
and mill product size distribution (d80). The results demonstrate a good dynamic response of the
model to variations in mill operational parameters. Thus, the model could be integrated in the
overall mill control scheme to assist mill operators and process engineers in timely decisions with
regard to mill control. |
