Modelling and Control of Ball Mill Grinding

Feb 17, 2018 The impulse response is calculated by a cross- correlation technique. Then a model involving a discrete transfer function and a time-series stochastic equation is calibrated using maximum likelihood methods. Experimental. A continuous grinding experiment is performed in a Denver 40 x 40 cm grate discharge ball mill.
