Jun 27, 2020 The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve.
Feb 13, 2017 The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
