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.

The IsaMill™ produces greater power intensity than ball or tower mills. Today's IsaMill™ is also light. A modest volume of concrete and structural steel are used, and the entire unit sits on a onestorey platform. This means it's about a third the height and weight of similar grinding mills available. It produces the most consistent and

For one, the ball charge and tumbling motion of a Bond mill is inefficient in this range. Also, screening well at 500 mesh is not easy. Many people overlook the impact of screening on the Bond results but the impact can be significant. The other issue is that nowadays fine grinding is not performed in tumbling mills for energy efficiency reasons.
