Stage 4: Finish Process

A typical general purpose Portland cement of fineness (specific surface) 340 m.kg-1 ground on an efficient closed-circuit ball mill system requires around 32 kWh per tonne, so a 10 MW mill would produce 313 tonnes of this per hour. In addition to the energy consumption of the mill, the "ancillary" equipment (separator, fans, conveyors Get price

Dynamic Behavior of Closed Grinding Systems and Effective

two reasons, grinding mostly is performed in closed circuits, where the product of the cement mill (CM) outlet is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to CM to be ground again.Get price
