Ball Mill Operatingspeed Mechanical Operations Solved The critical speed of ball mill is given by where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill is operated at 100 x 15307 4886 of critical speed Ball Mill Operation Manual Ball mill operation manual before ball mill operation you should verify that the lube oil pressures are within operating parameters check that the high pressure gangue on the bearings is within operating and check for any leaks on the air system for the clutch besides you should make sure that the gauges on the air system are within Ball Mills An Overview Sciencedirect Topics The ball mill is a tumbling mill that uses steel balls as the grinding media the length of the cylindrical shell is usually 115 times the shell diameter figure 811 the feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight
