Cement wear solutions
Kiln Inlet, Kiln Outlet & Cooler Wear Solutions
Heat-resistant liners for clinker discharge and cooler impact areas.
Kiln Inlet, Kiln Outlet & Cooler
Zone Introduction
Hot, partially calcined meal enters kiln → mix of heat, abrasion & impact. Wear is severe and concentrated in a compact area.
Hottest abrasion zone in Cement industry. Clinker drops at >1400°C → thermal shock + mechanical abuse.
How wear happens
Process Description
Material slides into rotary kiln while hot dust recirculates:
Any deformation → Feeding instability → Coating disturbance.
- Sliding abrasion Liner thinning
- Mechanical loading Stress cracking
- Gas erosion Surface roughness
- Free fall Impact failure
- Cooler airflow Oxidation & erosion
- Primary crushing in cooler Fragment abrasion
- Massive thermal gradients Cracks & deformation
Areas of Wear & Root Causes
- Impact pads Repeated strike erosion
- Transition welds Heat fatigue
- Cooler inlet chute Strike damage
- Grates & deck plates Thermal fatigue
Performance Loss & Downtime Impact
- Freeze or blockage risk
- Kiln over-temperature refractory damage
- Reduced cooler efficiency High clinker temp
- Kiln stoppage due to clinker blockages
- Costly large component replacement
