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. But, in the case of ball mill one can assume that the axial

01/04/1999 The discrete element analysis starts with a mathematical representation of the entities. Ideally the system should be simulated in three dimensions. But, in the case of ball mill one can assume that the axial motion in either direction is minimal so it can be simulated in two dimensions, where the mill is considered to be made up of several circular compartments containing one layer of balls

Discrete element analysis of tumbling mills ScienceDirect

The tumbling mill simulation problem has been intractable due to the multibody collision events involving thousands of balls and rocks. The harsh environment in the mill prevents any intrusion with measuring sensors. Simpler physical models with some empiricism could not describe the charge motion within the mill adequately. The discrete element method (DEM) provides a fitting solution to this
