Modelling And Simulation Of Grinding Mills

Modelling And Simulation Of Grinding Mills. Grinding mill modelling the studied model relates dynamically the mill discharge product size p to the mill feed rate f.Since the sampling interval is too large to characterize the dynamics of the mill discharge rate and percentage of solids, the models for these two variables are not considered here.
