2020-2-24applied DEM to the simulations of the charge motion in a 2D ball mill. Cleary and Sawley 19 simulated a 3D ball milling as a part of the DEM modeling of the industrial granular ows. Cleary 2021 is the pioneer in studying semi-autogenous grinding mills using DEM. Weerasekara et al.
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horiontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls.
Pit mine. The unit operations consisting of crushing grinding and flotation process about 65000 tons of ore per day in six overflow ball mills. The concentrate is transported to a smelter a few miles away. The crushed ore from primary and secondary ores is conveyed into bins.
This study used the discrete element method DEM which is effective and popular for solving the problem of granular systems simulating the motion of particles in a ball mill in different structural forms and at different rotational speeds.
In a stirred media mill the mill body is static and the charge motion is created by an agitator such as a rotating spiral or impeller.

Ball mill wear occurs as a result of the violent interactions within the ball charge.
First it is established that charge motion in ball and SAG mills can be computed with ease using DEM. The simulation results in the case of the ball mill are verified by comparing snapshots of charge motion.
2011-6-21Discrete 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.
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.
