The discrete element method for the simulation of ball mills

Nov 01, 1992  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 ...

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.

Feb 13, 2009  The results of discrete element method simulation were compared with actual grinding experimental results. The grinding rate constant K can be expressed as K=a exp(bn), where n is the rotation speed. To investigate the correlation between K and the simulation results, a new factor, the calculated force, was defined as F cal =average force acting on a ball coordination number.
