Ball mill classification system optimization through functional performance modeling by R.E. McIvor, K.M. Bartholomew, O.M. Arafat and J.A. Finch program (McIvor, 2005) and used for plant improvement work (for example, see McIvor and Finch, 2007, and McIvor, 2014). Now, by combining this business-friendly ball mill model

Advanced Controller for Grinding Mills: Results from a ...

slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or when the power draw drops below a preset value at nominal operating conditions. SmartGrind was installed on Mill No.5 and its performance was ...
