Use mesh motion on the cell zone to incorporate the motion of the mill. The next step is to create a Rocky (v4.3) model with your geometry and particles included. Then using the Fluent two-way CFD Coupling, import the case file into Rocky. The mill rotational motion will be automatically created and you need only to assign it to your geometry.

exception is the Morrell’s model (Morrell, 2008, 2009). In his approach the total speciﬁc energy of the entire AG/SAG circuit is ﬁrstly predicted using the SAG mill feed F80 and the ball mill cyclone overﬂow P80. Morrell’s model (Morrell, 2011) relates the feed, mill geometry and operating conditions to the speciﬁc energy of the ...
A Model Predictive Control System such as MillStar Advanced Process Control (APC) can continuously seek the optimum mill operation by changing the solids feed or load setpoint, e.g. by continuously determining whether the mill is overloaded or under-loaded. Safety controllers can be used to change the solids feed rate and feed water to prevent ...
