The power consumption is usually determined by charge fill level, lifter height, lifter number, and mill speed. However, almost all of the classical theories for calculating the power consumption of ball mills disregard the effect of lifters and only focus on rotation rate, charge fill level, as well as size and shape of grinding media, thereby ...

Effects of slurry filling and mill speed on the net power draw of a tumbling ball mill. The pool of slurry is known to lower the power drawn to the mill. An attempt to ascertain this observation by relating load orientation to mill power for a range of speeds and slurry fillings was undertaken. It was found that Morrell's model could. Cited ...

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 60–70% and slurry filling 0.84. An ...

effect of speed on tumbling mill power drawn. 01/02/2014· The experiments with the pilot mill showed that mill power drawn not only increased with slurry filling, but it also increased linearly with mill speed. This finding seemingly negates the assumption of a well-mixed load and rather suggests that the distribution of slurry inside the ...
