Aug 05, 2015· 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

The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure The speed of rotation of the mill influences the power draft through two effects: the value of N and the shift in the center of gravity with speed. The center of gravity first starts to shift to the left as the speed of rotation increases but
Critical Speed Equation In A Tumbling Mill. a ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sinteringt works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell ball mill.
