Detailed Production Process of Chrome Ore Powder/chromite flour/Chrome concentrate flour
- Grinding & Classification
- Ball mill / Raymond mill: grinding to 80–600 mesh (commonly 200 mesh / 325 mesh).
- Classification: spiral classifier / cyclone separator → coarse powder returned for re-grinding, fine powder for separation.
- Purification (Increasing Cr Content, Reducing Si & Fe)
- Magnetic separation: removing magnetic impurities (iron, silicon) → improving chrome grade.
- Flotation (for complex ores): reagents make chromite float while gangue sinks.
- Dewatering & Drying
- Concentration + filtration: thickener, filter press → reducing moisture.
- Drying: rotary dryer → moisture content < 1%.
- Sieving & Packaging
- Vibrating screen: sieved into grades including 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1200 mesh, 1600 mesh, 2500 mesh.
- Packaging: 25kg PP woven bags / 1MT jumbo bags.
