MILL CONTROL BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4 grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills.

In this respect, grinding performance of the air-swept ball mill was evaluated and modelled as a perfectly mixed single tank using the perfect mixing ball mill modelling approach (Whiten, 1974).

In an air-swept mill, the body of which does not differ significantly in general design from a trunnion overflow mill, a powerful stream of air is passed through the mill and removes the finer particles produced by the grinding process. This stream of powder-laden air is then passed through the classifier and the "oversize" material, rejected by the classifier, is returned to the mill with ...

Stable control of a coal-pulverizing system with ball-tube mill usually cannot be hold due to some disturbances, such as coal hardness and steel ball wearing, etc. A hierarchical structure with a direct control layer and a set-point optimization layer is applied to this typical system. Based on steady-state gain models of different operating points, a grid search method is employed to ...

Feb 20, 2005· This means that this modeling approach is a useful quantitative indication of what may occur in fully air swept mills. With more data set taken from the plants it would be possible to develop the relations between the model parameters and the mill operating conditions such as ball size distribution, mill load and grinding circuit configuration. 6.

The mill load of the industrial air-swept ball mill has till now been controlled by measuring the power consumption of the mill motor. Thus, it was necessary to operate far from the range of optimal mill filling. To improve the circuit performance, alternative ways of mill load measurement were investigated.
