The results are a stable circuit with mill and separator opti- mized, producing a consistent quality product of a predictable fineness. This enables one to use cement quality as the single circuit control set point. I. INTRODUCTION T HE MAJORITY of cement finish grinding is done by ball mills in closed circuit with a separator.

Apr 01, 2015 Static separator model. Grinding efficiency in ball mills depends on the classifying performance of air separators as explained in the study of (Klumpar and Slavsky, 1989) and (Kolacz, 1999). Their findings indicated that, energy consumption in ball milling can be reduced if the classification efficiency is sufficiently high.

Jul 31, 2014 These models can be used to simulate cement grinding circuits and to assist their optimisation. The “work horse” of the cement grinding plant is the two-compartment ball mill, commonly called the tube mill. Significant advances in model development were achieved in recent years (Benzer et al, 2001, 2003) through research on industrial scale.

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named “conscious laboratory (CL)”.
