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.

In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.

Ball mill is an energyintensive device for grinding and breaking iron ore particles, which is extensively used in mineral, cement, chemical, and other industries. 14 In the field of mineral processing, a portion of the energy is converted into heat that will raise the milling temperature and breakage characteristics of iron ore will be changed accordingly.

There are two wellknown modes in which the ball charge moves inside the mill: cascading and cataracting. 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 highimpact forces. It has been ...
