Mill Speed Control Using Programmable Logic Controllers

Mill Speed Control Using Programmable Logic Controllers

We obtain a critical speed of 0,37 Hz. Hence, critical speed in revolutions per minute is: c = n Hz ⋅ = 0,37 60 22,2 rpm In this case, critical speed is 22 rpm. But ball mills usually operate at 65% to 75% of the critical speed. Hence, operating speed is approximate 16 rpm. The mill is .

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. 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 An
