Raw Mill Feed Zones
Endure abrasion. Increase output.
Zone Introduction
Raw Mill efficiency directly influences kiln stability and final clinker quality.
Feed equipment must deliver uniform flow at constant rate.
Abrasion from fine raw material mix causes fast wear if unprotected.
Process Description
Mixed raw materials (limestone, shale, iron ore) pass through feed hoppers, rotary feeders and inlet chutes.
Wear mechanisms:
- Sliding abrasion from fines → Steel thinning
- Powder friction with moisture → Corrosion-abrasion
- Turbulent flow at bends → Localized groove wear
- Vibration → Weld cracking
Without proper liners, geometry changes → flow disturbance → process instability.
Areas of Wear & Root Causes
Inlet chutes & cone zones → Velocity erosion
Feed impact areas → Denting & gouging
Performance Loss & Downtime Impact
Fluctuating mill feed → Poor grinding efficiency
Higher kWh/ton consumption
Frequent liner change → Extended shutdowns
Recommended Products & Benefits
- Long life against fines abrasion
- Maintains smooth flow profiles
- Excellent resistance to high-speed fines
