If the method ofThe effect of processing parameters on energy,grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), theCharge behaviour and power consumption in ball mills,,01-08-2001· The change in power consumption between the best and worst lifter shapes is now 8.4%. ⋅ For a mill speed of 100%, the lowest specific power occurs for new lifters. Energy consumption increases as the lifters wear and is still increasing even at 22.5°, by which point it has increased by 16.5%.Ball mill media optimization - Metcom Tech,torque mill test is the mill energy input divided by the solids load. The energy specific cumulative grinding rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be,
