Using DEM to investigate how shell liner can induce ball

Jun 01, 2020· As for the coarse and small ball segregation, at 60% N c mill speed, weaker trends are observed as already discussed for Fig. 9. It is apparently possible that with longer simulation times, the segregation could become equally significant and thus longer simulation times are recommended with the possibility of reaching the equilibrium.

Predicting charge motion, power draw, segregation and wear

Nov 01, 1998· Simulation of ball, SAG, AG, pebble, tower and many other types of mills by discrete element methods offers enormous prospects for improving the efficiency and productivity of these comminution processes. In this paper we report the results of extensive DEM simulations of ball mills. This builds on earlier work by Mishra and Rajamani [7,8,9].

Using DEM to investigate how shell liner can induce ball

Three ball size classes are tracked for evidence of segregation at 75% and 60% of critical mill rotation speed. The ball distributions in the various segments at the end of 80 mill revolutions suggest that varying axial liner profile configuration can affect ball segregation, particularly for the mill running at 75% of critical speed.

Predicting charge motion, power draw, segregation and wear

Segregation is an important issue in rotating mills. Size segregation of steel balls and size separation of small rocks from the larger bails are examined. Predictions of liner wear rates and distributions are made. Evolution of the liner profile can be modelled in order to predict the lifter life cycle and its effect on the mill operation.
