A grinding circuit simulator has been constructed. The simulator is based on the kinetic model of grinding combined with scaling-up factors for various milling conditions, mass transfer raws, classifier models and the cicuit algebra. It is capable of predicting the production rates of the mills and the product size distributions for various grinding circuits. In order to test and illustrate the use of the model, an industrial grinding cirucuit for prouction of fine quartz sand was simulated. The basic model parameters were determined from the grinding tests using a small batch ball mill. The simulation results was in close agreement with the actual milling data.
