Ball Mills an overview ScienceDirect Topics

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of100 μm.This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.

Ball mill Ball mill factors influencing the size of

Ball millthat works on the principle of impact is an efficient technique ofsize reductionthrough grinding. Thesize reductionis an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties

SIZE REDUCTION AND SIZE SEPARATION

At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained byimpact of the particles between the balls and by attrition between the balls.Generally it is 0.5 cycles per seconds (cps).
