The program gives as output the calculated mill length, mill diameter, mill speed, ball load, hydrocyclone number and the size distribution in all of the circuit streams. As an example Select a mill to grind 425 tph of copper ore from a feed size of 80% passing 2360/~m to a product of 80% passing 210 ttm.

A ball mill mineral can be used to grind both wet and dry products and there are two types of ball mills namely over fall type and grate type depending on the different ways they discharge materials. There are also many types of grinding media and there properties are density, size, composition and hardness.

The discrete element method for the simulation of ball mills B. K. Mishra and Raj K. Rajamani Comminution Center, University of Utah, Salt Lake City, Utah, USA The discrete element method (DEM) is a proven numerical technique for modelling the multibody collision behavior of particulate systems.
