### Modelling and Control of Ball Mill Grinding - 911 Metallurgist

17-02-2018 This study shows that it is possible with appropriate experiments to find a dynamic linear empirical model of a continuous grinding ball mill the advantage of empirical modelling compared to phenomenological modelling is its ability to represent the experimental facts as they are without forcing them to obey a preconceived model

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

This means either your SAG mills are too big (or you have too many SAG mills) or your ball mills are too small (or you have too few of them) for a particular sample to grind efficiently. The model responds to this situation by reducing the circuit throughput to match the ball mill limit, and then reducing the total filling in the primary mill until the power draw matches the power draw ...
