%X The purpose of the study is to assess the grinding and classification performance of a conventional Polysius£¿ two-compartment ball mill and a Sepol£¿ dynamic air classifier closed circuit process at Portland CEMI/42.5R and Portland composite CEMII/32.5R cement production types. For this purpose, industrial scale sampling surveys were performed around the circuit. JKSimMet Steady State Mineral Processing Software was used to perform mass balance around the circuits. Size reduction performance of the ball mill was determined for the sampling cases. Classification performance of the dynamic air classifier was evaluated based on the efficiency curve approach. It was determined that, approximately 12% circuit capacity increase could be achieved in composite cement production when ball mill, ball mill filter and air classifier power consumptions were considered. This figure corresponded to overall energy savings of 7% in ball mill grinding
