Failure modes to watch for
Every guide in the FLSmidth FLSmidth Cross-Bar 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.
Uneven air pressure distribution across the grate compartments allowing hot clinker channels
Kiln burning zone instability causing lumpy or fine-rich clinker surges
Insufficient cooling air total volume for the clinker throughput rate
Grate speed too fast for current clinker production, thinning the bed and creating short-circuit airflow
Clinker inlet backed up and packing the crusher reducing available motor torque
Crusher roller or hammer bearing failure increasing drive resistance
Tramp metal from kiln brick or metallic debris jamming the crusher
Drive coupling worn or damaged absorbing input power

How to prevent clinker red river and snowman formation on a FLSmidth Cross-Bar cooler
Red river and snowman formation are caused by uneven airflow across the grate. Rebalance the compartment air pressures and adjust the cooler grate speed to spread the clinker bed evenly.
How to diagnose clinker crusher drive faults on a FLSmidth Cross-Bar cooler
A crusher drive overload trip usually means clinker is packing the inlet or a bearing is failing. Clear the inlet first, then check crusher bearing temperatures before restarting.
How to inspect and replace worn grate plates on a FLSmidth Cross-Bar clinker cooler
Excessive fall-through dust and hot particles under the grate mean worn or cracked grate plates. Schedule a grate plate inspection at the next kiln stop and replace damaged plates.
