High Vibration Ball Mill Duel Pinion Drive - Mechanical ...

A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor, gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.


Pinion Shaft - an overview | ScienceDirect Topics

The gearless drive design was not applied to the mills in the mineral industry until 1981 when the then-world's largest ball mill, 6.5 m diameter and 9.65 m long driven by a 8.1 MW motor, was installed at Sydvaranger in Norway (Meintrup and Kleiner, 1982).


How to install and align the girth gear and pinion | prmdrive

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS …

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.

Single pinion drive | Gear Units | Products | Flender

Ball mills and rotary kilns are most challenging applications that demand a big deal from the drive system. High performance and reliability are very important. When it comes to milling of iron ore, limestone and clinker large axial and radial forces occur. Single-pinion drives must be able to withstand the acting forces permanently.

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 …
