Cement mill Wikipedia

This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system. Capacity of cement mills. The cement mills on a cement plant are usually sized for a clinker consumption considerably greater than the output of the plant's kilns. This is for two reasons: The mills are sized to cope with peaks in market demand for cement. In temperate
