17 Signs of Problems with Ball Mills: Quickly Remove Hidden Troubles

Jul 20, 2022High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

Formula For Recirculating Load Of Cyclones And Mill

the cyclone overflow P80 size is generally suitable for these purposes. An example calculation of CSE follows: • Cyclone overflow product sizing is 80 percent passing 106 µm. • The ball mill feed is 60 percent plus 106 µm. • The ball mill discharge is 50 percent plus 106 um. • The circuit CSE is (60 percent + 50 percent)/2 = 55 percent.

Mill Steel Charge Volume Calculation Mineral Processing Metallurgy

While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below or approximated from the equation and calculation: % Steel Charge Loading in Mill = 113 126 H/ D
