    The tests covered a range of slurry filling (U) from 0 to 1.7 with media charge between 12 and 36 of the mill volume and six different speeds between 60 and 85 of critical speed. A power analyser was utilized to measure mill power. Increase in mill speed and ball filling leads to a remarkable increase in the amount of the power.
