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

Apr 01, 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.

##### The discrete element method for the simulation of ball mills

Nov 01, 1992  Discrete element method in modelling ball mills: B. K. Mishra and R. K. Rajamani Material stiffness The material stiffness was determined in an apparatus known as the "ultrafast load cell," an apparatus used by Hler and Herbst' for particle bed breakage studies. It consists of a 5-m-long steel rod in which fastresponding strain gauges are embedded.

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

The motion of the charge is rigorously simulated with a numerical technique known as Discrete Element Method (DEM). In this technique, the coordinates and velocities of each individual ball are computed from a knowledge of forces arising when balls collide with each other and with mill shell and lifter walls.
