Run the IsaMill™ empty (no water or media) for 510 minutes to warm up the bearings and seal. Then proceed to run the mill empty at 1500rpm for an additional 10 minutes and measure the cumulative power draw using the watthour meter (Wh) and stop watch. From the time and total energy values, the no load power draw can be calculated.

A power model for fine grinding HIGmills with castellated rotors
Introduction. Fine grinding in stirred bead mills is becoming increasingly common in the mineral processing industry. Typically they are used as regrind mills in concentrator circuits where the reduced volume of highgrade ore justifies the high energy input, however they are now also being considered for some duties previously performed by ball mills (Capstick and Currie, 2012).
Ball Mills 911 Metallurgist
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
