Recent decades have proven the great effectiveness of a vertical roller mill for grinding raw materials.Mill. Cement and Concrete The results show that the energy input is better utilized in mills that work by attrition or by combined impact and attrition. when grinding in a ball mill. Ball Mill Operating Principles Components Uses
finish grinding of Portland cement slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills and in comparison with traditional ball mill operations the energy requirements for the OK cement mill is 30-45 percent lower for cement grinding and 40-50 percent lower for slag. The OK mill can contribute significantly to profitability and
