Optimization of continuous ball mills used for finish

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.

Optimization of continuous ball mills used for finish

The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.
