Ball mill length = 4.57 m. Ball mill diameter = 4.57 m (inside liner diameter = 4.39 m) Ball mill load = 35%. Ball charge mass = 113 t. Ball size = 64 mm. Step 5. The diameter efficiency factor, F 3, in step 2 can now be determined using Equation (8.10) (Figure 8.10). As the ID of the mill has been provisionally established as 4.39 m, then

Ball Mill Pedestal Vibration The highest amplitude of vibration on the ball mill drive was recorded in the axial position on the drive end motor bearing; with a amplitude of 7.7 mm/s rms at 60Hz. The source of the vibration emanates from the pinion gear mesh frequency (GMF) i.e. 18 teeth X 200 rpm ÷ 60 = 60Hz. However, GMF by

Vibration at the ball bearing housing of the ball mill is a device failure that affects the normal operation of the ball mill. There are many reasons for causing low-frequency vibrations, and the vibrations and hazards caused by their respective causes are also different. There are various repair methods.

"The pinion drives the trunnion; it's what makes the ball mill turn. The pinion is a small gear with a matching tooth profile to the ring gear on the ball mill. From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill.

I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling on …
