Optimisation in the US | World Cement
Ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have drying function besides grinding.

GRINDING AIDS Raw meal grindinga ids: improvingbu rnability
remain the same.3 Therefore, cement plants need to determine the ˚neness level required to ensure good combinability without overgrinding the raw meal, and wasting energy and capacity. Plants have typically achieved this by setting targets for the 90 and/or 200µm sieve residue of the raw meal, but this does not present the whole picture.
