RMHS — Crusher / Unloading / Conveyors
Control dust. Protect the process.
Zone Introduction
Raw Material Handling System (RMHS) receives iron ore, coke, limestone, and flux materials from wagons and trucks. These are crushed, screened, and conveyed across long distances.
Each transfer point releases heavy ore dust, coke dust, and fine silica.
Dust Generation Mechanism
- Material falls from height into hoppers → High-velocity dust clouds
- Conveyor loading, belt impact → Fugitive dust escape
- Crushers breaking hard ore → Visible respirable dust
- Dry weather increases dust release
- Airflow inside buildings → dust migration into surrounding zones
Root Causes
Multiple drop points without sealing
Screens and crushers operating dry
Belt vibration → Gaps around skirting
Dust suction inside tunnels due to pressure differential
Regulatory + Production Impact
Restricted workplace visibility → Unsafe operations
Respiratory health risks → Silica exposure
Dust settling on motors, bearings → Premature failure
Housekeeping shutdowns → Direct production loss
Non-compliance with pollution board limits → Heavy penalties
