The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

Based on a dynamical model of the grinding process in closed circuit mills, efficient efforts have been made to optimize PID controllers of cement milling. The process simulation is combined with an autoregressive model of the errors between the actual process values and the computed ones. Long term industrial data have been used to determine the model parameters. The data include grinding of ...

Our results suggest that integrating an air classifier into an opencircuit ball mill can increase the production rate by 15% or increase the cementspecific surface area by 13%. A singlecompartment mill entails a premilled feed for proper operation, whereas a twocompartment mill yields a finer cement product than a threecompartment mill.
