The dynamic analysis of the charge inside the ball was done using Discrete element, EDEM software which resulted in the time varying load applied on the drum. This load was then applied to the FE model using ANSYS software for dynamic analysis of the ball mill structure. The ball mill was modeled in Autodesk Inventor 17.

Analysis of Power Draw in Ball Mills by the Discrete Element Method. 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 ...

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.

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.
