FLSmidth FLSmidth ROTAX-2 at a glance
The Dovient library currently covers 3 published troubleshooting guides for the FLSmidth FLSmidth ROTAX-2, with 20 individual procedure steps distilled from OEM manuals and field experience. On average, a fix on this machine runs 7 steps and roughly ≈1 hr on tools. Complexity is classified as heavy, the average fix on this machine runs multiple hours, touches several sub-systems, and is usually planned work rather than reactive.
Failure modes to watch for
Every guide in the FLSmidth FLSmidth ROTAX-2 library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Support roller skew angle drifted from the design value during thermal cycling
Thrust roller bearing failure allowing uncontrolled axial movement
Uneven support station loading from a settling foundation causing the kiln axis to deflect
Excessive tire migration from loose tire fit amplifying the axial load on the thrust roller
Thermal shock from rapid kiln start or stop cracking the brick
Brick wear from long operating campaigns without refractory inspection
Coating spall from kiln upsets exposing the brick to direct flame
Misfire or incorrect flame shape impinging directly on the brick surface
Tools you'll need most
These tools are referenced most often across the FLSmidth FLSmidth ROTAX-2 troubleshooting guides. If you service this equipment regularly, keep them on the cart.

How to measure and correct kiln tire shell ovality on a FLSmidth ROTAX-2 rotary kiln
Excessive tire ovality flexes the kiln shell and cracks the refractory. Measure the tire stop position and the tire-to-shell gap, then adjust the tire position to correct ovality.
How to detect and respond to refractory brick failure on a FLSmidth ROTAX-2 rotary kiln
A hot spot on the kiln shell means the refractory brick has failed in that zone. Stop the kiln immediately if the shell temperature exceeds the maximum safe value to prevent shell distortion.
How to detect and correct kiln thrust roller misalignment on a FLSmidth ROTAX-2
Excessive axial kiln migration means the support rollers are not skewed correctly to control axial float. Adjust the roller skew angle in small increments and monitor migration response.
