Ball Mill Pinion - Vibration Analysis & Machinery

Actually, I think Danny is onto something. Mill speed = 180 x 24/241 = 17.925 107.67 / 17.925 = 6.007 so the sideband frequency is 6X the mill speed. Does the bull gear have 6 segments? Is the bull gear mounted above the pinion, or to the side? Is this a horizontal ball mill with large brass sleeve bearings
