The use of predictive control on cement grinding circuits based on statistical models obtained by process identification has proven more efficient as compared to the more conventional fuzzy control (Knudsen, 2004). The purpose of this study is to develop a simple first principles model description of a cement grinding circuit for control purposes.

"Large production machines generate a lot of dust, so the CFM of the system has to be able to keep up. Smaller grinders and polishers can have lower CFM airflows. Some manufacturers rate their systems with a 2-inch hose connection and some with a 3-inch connection, so it really depends on the demand of the grinding equipment.
