Kiln Inlet, Kiln Outlet & Cooler
Endure abrasion. Increase output.
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.
Process Description
Material slides into rotary kiln while hot dust recirculates:
- 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
Any deformation → Feeding instability → Coating disturbance.
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
