A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

The power required to drive a tumbling mill is of interest both to the designer and to the mill operator: to the former as a basis of design for the determination of the necessary size of the elements of the machine; and to the latter because all other factors being equal, the most economical machine is that which demands a minimum power for driving.
To study the effect of lifter shapes on mill power, a DEM model (∅ 520×40 mm) with 24 pieces of lifter was established. As shown in Figure 1, the lifter was designed with three different ...

2014). However, the horizontal planetary ball mill is different than the tumbling ball mill in many aspects. Djordjevic (2005) studied the influence of ball charge size distribution on the net-power draw of tumbling mill based on DEM modeling. Charge of the mill was composed from the spherical balls
For the mill with higher mill load and lower speed, the power draw of the mill differed slightly for the different lifters with the same face angles of 20o. Rail lifter drew higher mill power and lower power for Hi-Lo lifter. The Hi-Lo lifter relatively indicated improvement in the energy efficiency of the mill approximately 22%.
Tumbling mills mill power draw wet grinding mill speed slurry filling Date received 20 October 2014 accepted 6 July 2015 the rotation up to 100 of the critical speed. In each experiment the mill was allowed to work for several rotations and the power was recorded over time.
A power analyser was utilized to measure mill power. Increase in mill speed and ball filling leads to a remarkable increase in the amount of the power. Preliminary results show that there is a definite trend between the power and the slurry filling U. Mill power draw is maximum at slurry concentration 60–70% and slurry filling 0.84.
