axial transport in dry ball mills

Cleary [80] consideredaxial transportandgrate dischargein adry ball milland showed that in the absence ofair flowthat this is a slow diffu- sion process. Cleary et al. [81] examined the effect of feed size on the en- ergy utilisation incement ball mills. ...

Ball mills are used for grinding of rocks, cement clinker and limestone from10to 100 mm feed sizes down to sub-millimetre product. They are typically rotating cylinders with diameters from 3 to 6 m and lengths from6 to 12m.

Axial transport in dry ball mills- cfd- critical speed forball mill,12 dec 2003 , in the front to allow themill internalsto be seen the fill level was 30 by volume and themill speedwas 75 of the critical speed required to centrifuge particl the charge consisted of rocks andballs, withballs makeffectof operational variables onball.

In this paper, we examine theaxial transport in dry ball mills. This requires simulation of the entiremilland the full volume of the charge for significant periods of time (thousands of revolutions). We use a simple model forgrate dischargethat allows prediction of the time varyingaxialdistribution of different particle sizes within adischarging ball mill. The distributions of sub-grate size ‘fines’ is shown to …
