The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The cataracting motion, on the other hand, causes the particles to break under high-impact forces. It has been shown that cataracting motion alone is not sufficient for effective grinding.

The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Diverse ball milling conditions were employed by changing ball size, media charge, mill speed, and slurry holdup in order to study the effect of polymeric dispersant aids on the grinding of dense slurries. In the absence of a dispersant, as the pulp thickens, there occurs an increasingly disproportionate split of the grinding charge between cascading and cataracting-centrifuging …

The motion of grinding bodies in conventional ball mills has been repeatedly investigated, both theoretically and experimentally. It is well‐known that, depending on mill filling and speed of rotation, different motion patterns occur and some of these patterns, especially that of cataracting, can be described by simplified theories.

As the shell of a ball mill is rotated, its grinding balls move in a cataracting mode, hitting on the powder bed, and cement clinker particles are broken down to smaller sizes. In closed-circuit mode, ball milling operation and external air classification are coupled (see Fig. 1).
