Ball Mills

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied.

Rod mills, how they function

Sep 01, 2013· 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.
