Effect of lifters and mill speed on particle behaviour ... The torque and power of a ball mill usually increase with an increase in mill speed when no lifter exists in the mill (N l = 0 or H L = 0 mm). Usually, the slope is extremely small. The torque and power curves become close to the curve corresponding to no lifters (N l = 0 or H L = 0 mm) when the lifters are few and low. This condition indicates ... Author: Xiaolei Bian, Guoqiang Wang, Hongdi Wang, Shuai Wang, Weidong LvCited by: 22Publish Year: 2017Horsepower V.S. Torque - Practical Machinist AC motors driven by VFD's tend to be constant torque devices. That's the typical mill spindle motor. A constant torque motor will develop horsepower in direct proportion to rpm. So, if you have a mill that's rated 20hp at 8000 rpm, it'll have 10 hp at 4000 rpm, or more significantly, about as much horsepower as a sewing machine motor at 100 rpm.
