Robust Model Predictive control of Cement Mill circuits
The present work considers the control of ball mill grinding circuits which are characterized by non-linearities and disturbances. The disturbances are due to large ariationsv and heterogeneities in the feed material. Thus the models obtained by simple tests on these mills are subject to large uncertainties which may result

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

Extraction of Zinc: Process, Methods, Diagarm, Examples
The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
