ROM Hopper — Run of Mine Hopper
Built for harsh mines. Proven to last.
Zone Introduction
ROM Hoppers are the very first receiving point for mine output.
Large, heavy rocks are dumped directly from trucks or shovels.
This area sees extreme impact + gouging + abrasion.
Any stoppage here halts the entire plant’s production flow.
Process Description
Run-of-mine ore contains varying hardness with silica and sharp cutting edges.
Hoppers continuously receive large boulders from high drop heights.
Wear mechanisms:
- Heavy impact loads → Denting, buckling & cracking
- Continuous abrasion from sliding → Steel thinning
- Sharp edges → Gouge marks & chips
- Vibration cycles → Fatigue failures
- Moisture converts fines → Slurry erosion
24/7 feeding → even thick steel plates lose integrity fast.
Areas of Wear & Root Causes
Hopper base plates → Impact & bending
Side wall liners → Sliding abrasion
Discharge lips → Turbulence erosion
Performance Loss & Downtime Impact
Breakthrough holes → Material spillage
Blockages → Loading delays → Lost productivity
