Optimisation of a coal pulverising mill gearbox
A mill gearbox must stay stiff under heavy load. We found where it flexed and showed how to stiffen it with small changes.

The challenge
The gearbox of a coal pulverising mill works under heavy, changing loads. The team needed a structural and vibration assessment, and ways to reduce displacement and raise stiffness.
What we did
- Prepared a finite element model of the gearbox.
- Ran structural analysis for static and dynamic loading conditions.
- Carried out modal analysis to find the mode shapes and vibration characteristics.
- Identified the bottlenecks and suggested modifications.
The outcome
Modifications such as added ribs and increased weld size were suggested, lowering displacement and increasing stiffness.
