This paper focuses on the use of a numerical tool known as the discrete element method (DEM) to study the motion of ball charge in ball mills. DEM is employed to simulate the motion of individual balls. While doing so, the effect of liner design on the grinding performance of the mill is studied.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Discrete Element Method simulation of charge motion in ball, SAG and autogenous mills has become a standard for lifter design, power draft evaluation, etc. Both two-dimensional and three-dimensional codes are being used. The two-dimensional code dominates the user market since the code completes a simulation in one …

The purpose of this paper is to establish that discrete element modeling is capable of handling multibocly collisions and, hence, accurately establish the motion of balls inside the mill which in turn drives the calculation for the power draw of the mill. SIMULATION OF CHARGE MOTION IN BALL MILLS.

Simulation of Size Reduction in Ball Mills and DEM. ... The key problem here is that we can very quickly set up a simulation of a tumbling mill: the geometry and the motion are simple and the media are spheres! As soon as simulations start running, they look very lifelike. ... In the case of ball mills, this is certainly not straightforward.

Jun 12, 2019· This paper addresses this gap by studying charge motion, and how the use of a magnetic liner affects the breakage mechanism of the mill, using discrete element method (DEM) modeling and the Hertz-Mindlin contact model with relative velocity dependent (RVD) rolling friction. Charge motion was modeled under different mill speeds.

The transport of slurry within the ball mill depends on the peripheral velocity and porosity of the ball charge. Residence time distribution and mill hold up are often used as indicators of the mode of transport. In this work, the transport problem is tackled via direct simulation of the three dimensional motion of the ball charge.
