FLSmidth FLSmidth ILC / SLC-D at a glance
The Dovient library currently covers 3 published troubleshooting guides for the FLSmidth FLSmidth ILC / SLC-D, with 21 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 ILC / SLC-D 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.
Alkali sulfate and chloride compounds cycling in the preheater condensing on cooler duct walls
Insufficiently bypassed alkali allowing buildup concentration to increase
Wet feed or high moisture in the raw meal raising condensation risk
Duct refractory surface roughness acting as nucleation sites for coating growth
Raw meal build-up accumulating in the cyclone cone from moisture-rich feed
Alkali sulfate rings forming inside the cyclone cone narrowing the throat
Feed surge overloading the cyclone capacity causing material compaction
Cooling after a kiln stop causing condensation that cements loose material

How to respond to a calciner fuel supply trip on a FLSmidth ILC / SLC-D
A calciner fuel trip causes rapid drop in calcination temperature. Identify whether the trip was a fuel supply failure or a burner fault, then restore fuel safely following the light-off procedure.
How to clear a cyclone blockage on a FLSmidth ILC / SLC-D preheater tower
A blocked preheater cyclone must be cleared promptly to prevent raw meal buildup and damage. Use the air cannon first, then the manual lance procedure if airflow does not restore.
How to remove riser duct coating buildup on a FLSmidth ILC / SLC-D preheater
Riser duct coating forms gradually from alkali sulfate condensation. Remove it during a planned kiln stop using mechanical lances. Monitor with pressure drop trending to schedule the next clean-out.
