Cement grinding Vertical roller mills versus ball mills
There are a number of ways to adjust the inclination of the particle size distribution curve for cement ground in an OK mill. In order to reduce the circulation factor, the grinding track on the grinding table has an upward curved shape that helps to retain a certain minimum amount of material under the rollers.
