Preheater / Cyclones
Endure abrasion. Increase output.
Zone Introduction
Cyclones handle hot raw meal and high-velocity dust-laden gases.
Any internal wear → pressure imbalance → higher fuel cost.
This is among the most aggressive abrasive zones in a cement plant.
Process Description
Hot raw meal is carried upward by exhaust gases.
Wear environment:
- Dust particle impact → Erosive abrasion
- Alkali compounds → Chemical corrosion
- Thermal cycling → Cracking & liner detachment
- Spiral gas movement → Violent particle collisions
Critical sections wear out quickly, causing internal leaks.
Areas of Wear & Root Causes
Cyclone dip tubes → High dust velocity
Riser ducts → Turbulent erosion
Inlet scrolls → Directional strike wear
Performance Loss & Downtime Impact
Heat loss → Increased fuel consumption
Accumulation & choking → Kiln feed instability
Unplanned shutdowns → Heavy production loss
