Abstract
This report presents the results of an investigation of comminution process simulation and scaleup of parameters in the population balance grinding model. It was found that grinding kinetics are highly correlated with the net power input to the mill. A normalized form of the model in which the energy input per unit mass of material being ground is the independent variable was obtained and this provided relatively accurate predictions of the product- size distribution over the normal range of ball mill operating conditions. Experimental data obtained in three different mills demonstrated the usefulness of this form of the model in the scaleup design of ball mills. Material flow through continuous ball mills was studied in mills of different lengths by using tracer techniques. The adequacy of the lumped-parameter population balance model for the simulation of the open circuit grate discharge ball mills at steady-state is demonstrated. Useful engineering design scaleup criteria are established and their applicability evaluated.
