Effect Of Speed On Tumbling Mill Power Drawn

FOB Reference Price: Get Latest PriceGet Latest Price

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. Preliminary results show that there is a definite trend between the power and the slurry filling U. Mill power draw is maximum at slurry concentration 6070 and slurry filling 0.84. An.

  • Effect Of Grinding Media Charge On Mill Power Draw Kw

    Maximum power is drawn by a mill when the charge occupies approximately 50 by volume. The power curve becomes very flat in the range above 45. As a result, mills are seldom run with charge levels greater than 45. In rod mills, the charge is swollen by particles of feed which separate the rods. If the mill is shut down immediately after the feed is shut off, the charge level will be greater.
