Limestone Crusher / Yard — High Dust During Crushing
Stop the dust. Increase packing efficiency.
Zone Introduction
Crushing limestone is the first step in cement manufacturing. When hard limestone is broken down into specified size, heavy airborne dust is released continuously.
Dust Generation Mechanism
Crushers break large limestone → Cloud-like dust formation
Drop from shovel → hopper causes impact dust
Belt feeding → Rebound dust escape
Open yard → Wind spreads dust over long distance
Root Causes
Dry material with sharp fines
Wind turbulence in open crusher area
No sealing at chute openings
Inadequate dust extraction systems
Regulatory + Production Impact
High respirable dust → Health hazard for operators
Visibility reduced → Unsafe machine operation
Dust settlement → High maintenance for motors, bearings
