A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

However, it is now feasible to model a periodic section of a laboratory scale ball mill and include the coarser end of the ore size distribution directly in the DEM model. This provides the opportunity to better understand the effect of media on the interstitial bed of powder and of the effect of the powder on the media. The effect of the ...

To be fully conclusive, however, these labscale mill results need to be complemented with others obtained from largescale ball mills used in actual concentrator plants. 5. Conclusions. A detailed characterization of chalcopyrite ball mill grinding processes, in both batch and continuous flow processing modes, has been carried out in this work.

In this paper, a laboratoryscale ball mill is employed in investigating the impact of different operating variables on the impact behavior of lifter. The determinations of ball trajectory, impact force and power draw are used to characterize the impact behavior between the charge and lifter. The main research conclusions are summarized as follows.

The toe angle was inversely proportional to ball filling, but the impact point angle was appeared to invariant to ball filling and inversely proportional to mill speed. By means of motion analysis of the charge, a good grinding efficiency can be obtained when the ball filling ranging from 20% to 40% and the mill speed ranging from 70% to 80%.
