Limestone Crushing
Endure abrasion. Increase output.
Zone Introduction
The limestone crushing area is the first contact point for raw material arriving from the quarry. Large, hard, abrasive limestone boulders break down into smaller sizes for raw mill feeding. Any disruption here immediately affects the entire cement process. High impact forces and constant material movement create a severe wear environment.
Process Description
Run-of-quarry limestone contains silica and irregular sharp edges.
Material drops into hoppers and crushers generating:
- High-energy impact causing dents and cracks
- Continuous abrasion as limestone slides over surfaces
- Moisture + fines → Corrosion + slurry wear
- Vibration-induced fatigue failure in liners
Crushing works 24/7 → even thick liners wear thin quickly → risk of breakthrough holes.
Areas of Wear & Root Causes
Hopper floors → Heavy impact bulging
Feed and discharge chutes → Abrasive cutting
Crusher inlet zones → Gouging of liner plates
Performance Loss & Downtime Impact
Blockages slow down feed → Crusher overload
Chute leaks → Unsafe & high cleanup time
Frequent repairs → Lower availability & higher cost
