Pinion bearing damage in ball mill. Using HD measurement technologies, Bulgarian copper producer Asarel Medet AD monitors the mechanical condition of critical equipment in the open-pit mine and flotation plant. This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.
Pinion Shaft is the key component in the transmission system of the mill, especially the large-scale SAG mill, AG mill and ball mill. It has strict requirements for material and manufacturing, complex process flow and high precision. Therefore, the selection, technology and manufacture of pinion shaft reflect a certain industrial level.

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 …
High vibrations on a ball mill. Hello everyone, I have a problem with high levels of vibration at the supports of the pinion (fixed and floating bearings) of the cement ball mill. The kinemantic scheme with the measurement locations and several representative spectra and timewaves are in the attched file. The dominant vibrations are in the ...
Pinion module of ball mill: Module is the ratio of pitch t to PI (m = t/ PI) between the teeth of the same side of two adjacent gears, measured in millimeters. Modulus is one of the most basic parameters in gear manufacturing. The larger the modulus is, the higher the tooth is, the thicker the tooth is. National standard ball mill pinion module ...

mill girth gear driving by torsion shaft and. mill girth gear driving by torsion shaft and. Ball Mill Maintenance Installation Procedure . The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. at the discharge end of the mill, and facing the mill, if the drive is on the right hand side it is a right hand mill.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
