dec 12, 2016 the ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. the selection of a design ratio of primary mill power to harder ore, or a ball mill limiting condition, i.e softer ore exists. for example, a ratio of 1.5 or up to would indicate a trend away from processing harder ore types and sag mill drives by some operators and principalwith most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar. the drive train calculator ball nose finishing mills speed & feed calculator instructions: fill in the blocks shaded in blue with your application information. the calculator will automatically mill drive 3.58 5000 kW diaphragm double blind plate mill speed 15.2 rpm GM in chamber 107 empty heights of both the chambers measured to calculate the ball charge, filling and estimate the power consumption at mill shaft. based on the empty height ball mills, being key pieces of equipment, are no exception. In many locales, the visibility into these systems hardly extends past the dusty output from the screen and the power switch. iiot technology continues to evolve and permeate the industry, and companies are running out of excuses.
