Stage 4: Finish Process | Cement Production

The output achieved by a ball mill system varies with the mill power, the fineness of the product and the hardness of the clinker. A typical general purpose Portland cement of fineness (specific surface) 340 m².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.
