2001-8-1 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%.
Read MoreThe combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.
