Key points in iron ore crushing line design include: thorough analysis of ore characteristics (hardness, abrasiveness) and precise selection of multi-stage crushing equipment (jaw crusher for primary, cone crusher for secondary/fine crushing).
Crushing and processing technology of iron ore
JOYAL Mining, as an integrated supplier of complete ore crushing solutions and equipment, has rich experience in iron ore crushing and has achieved technological upgrades for many large-scale iron ore projects, effectively improving ore grade and increasing economic profits.
Process Flow
High-Level Storage Silo → Vibrating Feeder → Jaw Crusher (Primary Crushing) → Iron Remover → Cone Crushers*3 (Secondary & Fine Crushing) → Vibrating Screen → Finished Product (Oversize material returns to cone crushers)
