milling to media ratio

ATTRITORS AND BALL MILLS HOW THEY WORK Robert E. …

Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

Optimum choice of the make-up ball sizes for maximum ...

As the size reduction ratio increases, the optimum ball ratio moves towards more small balls. At the finest grinding with a size reduction ratio of 128:1 (Fig. 7d), a 50.8 mm/25.4 mm ball mix at a 13:87 ratio was found to be the optimum mix. This indicates that the finer the product size, the higher the proportion of smaller balls that is required.
