Simulation of Size Reduction in Ball Mills and DEM

The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.

A Study of Charge Motion in Rotary Mills, with Particular .

The motion of balls deep within the charge of a rotary grinding mill was investigated. Novel investigative techniques were used to track the motion of the balls, including X-ray filming at 50 frames per second of both the front and side views of a transparent mill, and gamma-camera filming of a radioactive ball. Analysis of the trajectories of the

A review of computer simulation of tumbling mills by

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. Furthermore, it is shown that power draw of ball as well as SAG mills can be predicted within 10%.

Study on the Performance of Ball Mill with Liner

The results were as follows: when the rectangular lifter was selected as mill liner, the ball mill efficiency was significantly high. The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage.

In experiment, there is a steady, cylindrical-like air core formed in the center of hydrocyclone. Such dif-ferences between experiments and simulations might be because air core impact is not considered in simulation.

Modeling of comminution processes in spex mixer/mill

In the present work a mathematical model which is able to quantitatively describe comminution processes in a ball milling system (i.e. spex-mixer/mill) has been developed. The proposed approach takes into account three different contributions: dynamics of the vial, dynamics of spheres motion and simulation of the comminution process.
