### Dynamic Modelling Of Temperature In A Wet Ball Mill Based

Sep 01, 2019 Where, P is the power input (kW) to the mill, F f is the feed flow rate into the mill (fresh feed + dilution water), T f is the temperature of the mill feed, T d is the temperature of mill discharge, Q Loss is the rate of energy loss to the environment (kJ s), y fi is the mass fraction of mill feed solids in size class i while y pi is the mass fraction of mill product solids in size class i.
