Trajectories And Impact Velocities Of Grinding Bodies In

The motion of grinding bodies in conventional ball mills has been repeatedly investigated, both theoretically and experimentally. It is wellknown 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.

The aim of this paper was to study the transitional phenomena between cascading, cataracting and centrifuging motion. In order to observe these transitions, experiments were carried out in a tumbling mill of 300 mm diameter, and three sizes of chrome steel balls were used as grinding media. Each size of ball was employed in three different ...

Feb 27, 2019 The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated ball mills.. Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing. The term ball mill is restricted to those having a length to diameter ratio of 1.5 to 1 and less.
