Iron Ore Crusher

The Critical Role of Crushing in Iron Ore Beneficiation

Iron ore processing demands rugged, high-capacity crushing equipment to handle abrasive hematite (Fe₂O₃) and magnetite (Fe₃O₄) ores. Liming Heavy Industry designs Iron Ore Crusher specifically engineered for:

• Throughput capacities up to 8,000 TPH
• Ore hardness up to 300 MPa UCS
• Feed sizes ≤ 1,500mm

Stage 1: Primary Crushing – ROM Ore Reduction

• Challenge: Breaking massive iron ore lumps with high abrasiveness
• Solution:Gyratory/Jaw Crusher with reinforced structures
  Liming Equipment:
  • HGT Gyratory Crusher (e.g. HGT1385)
    • ≤1,500mm feed size for Australian Pilbara ore
    • 40% higher capacity vs traditional gyratories
  • C6X Jaw Crusher (e.g. C6X160)
    • ≤1,000mm feed opening
    • MX manganese jaws with 3x lifespan

Stage 2: Secondary Crushing – Size Reduction

• Challenge: Reducing ore to 30-50mm for AG/SAG mill feed
• Solution:Hydraulic Cone Crusher
  Liming Equipment:
  • HPT Multi-Cylinder Cone Crusher (e.g. HPT500)
    • Laminated crushing for taconite processing
    • Automatic iron discharge system
  • HST Cone Crusher (e.g. HST315)
    • ≤25mm output for pellet feed preparation

Stage 3: Tertiary Crushing – Fines Generation Control

• Challenge: Producing 6-10mm sinter feed with minimal slimes
• Solution:Fine Cone Crusher with precision settings
  Liming Equipment:
  • HPT300 Fine Cavity
    • Hydraulic CSS adjustment (±1mm)
    • -0.075mm generation <12%

Integrated Material Handling

• S5X Heavy-Duty Screen (e.g. S5X3075-3)
  • 3,500 TPH capacity for scalping
• B6X Belt Conveyor
  • Impact idlers for 200mm lump protection

Technical Advantages for Iron Ore Applications

Plant Configurations by Iron Ore Type

Brazilian 5,500TPH Project Data:

• Ore: Hematite (Abrasion Index 0.38)
• Final Product: 92% <32mm
• Wear Cost: $0.003/ton for HPT600 mantles
