Simulation of charge motion in ball mills. Part 2
Here, the model is used to simulate the charge motion in an industrial size mill. Many unobservable facts about charge motion are revealed by this simulation approach: It is shown that larger balls segregate to the center at high speeds and to the shell at lower speeds. The frequency of collisions in a 4.75 m diameter mill mostly lie within one joule. The friction between the ball charge and

A Review of Advanced Ball Mill Modelling
A Review of Advanced Ball Mill Modelling In the early 1990s the discrete element method (DEM) was used for the first time to simulate media motion in tumbling mills.

Ball mill Wikipedia
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. The axis of the
what is meant by ball mill
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material
