## Analysis of power draw in ball mills by the discrete ...

01/04/1999 Therefore, the discrete element method is a suitable choice for modeling the internal dynamics of ball mill, where balls and the mill shell are treated as geometrically inviolate elements. The discrete element analysis starts with a mathematical representation of the entities. Ideally the system should be simulated in three dimensions.

1 Abstract: Discrete element (DE) simulation of a ball mill with a large number of particles is challenging when each 2 particle is considered. Similarity principle could be adopted to reduce the number of particles in a simulation whilst 3 still maintaining the accurate flow behaviour of particles.

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge.
