the circulation load is monitored by weighing the flow of reject material from the separator. These measures ensure you achieve optimum mill performance efficiency and cement bulk device for cement canning leaving factory. Flow SheetThis is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.The paper focusses on improving the energy utilization of a cement grinding circuit by changing the flow sheet of the process. The circuit was comprised of ball mill
