optimisation optimisation of the ball charge in mills

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.

2004-12-10  The optimal L/D ratio range is quite broad again with the minimum in the range of 3.2. For one compartment mills, this optimum should be less due to the lack of the first compartment used for coarse grinding. The optimal ball charge filling ratio for Combi-ball mills is supposed to be less too.
