Get PriceA deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods.

Get PriceDiscrete element method. The DEM is a numerical method to address the kinematic and mechanical behaviour of complex granular systems involving many discrete units with certain shapes and masses. It has been widely used in ball mills [18,36] to determine the particles behaviour and the torque and energy of ball mills in different working.

Get PriceHowever, despite the usefulness, DEM simulation studies have not been applied widely to the high speed stirred mill system like IsaMill. This paper presents a numerical investigation of the flow of grinding media in a simplified IsaMill, aiming to examine the feasibility of using DEM simulation to predict particle flow in a high speed stirred mill.
