Chrome Ore Crusher

The Critical Role of Crushing in Chrome Ore Beneficiation

Chromite (FeCr₂O₄) requires precise size reduction to liberate chrome spinels while minimizing fines generation. As a global leader in mining equipment, Liming Heavy Industry engineers Chrome Ore Crushers optimized for ultra-hard, abrasive chromite ores with unconfined compressive strength (UCS) up to 300 MPa.

Stage 1: Primary Crushing – ROM Ore Reduction

• Challenge: Breaking massive chromite lumps (≤800mm) with high toughness
• Solution: Heavy-duty Jaw Crushers with reinforced structures
  Liming Equipment:
  • C6X Series Jaw Crusher (e.g. C6X145)
    • Eccentric forged shaft for 560mm feed size
    • 35% longer jaw plate life with MX manganese steel
  • PE Series Jaw Crusher (e.g. PE1200×1500)
    • ≤220mm output for South African UG2 ore

Stage 2: Secondary Crushing – Chromite Liberation

• Challenge: Achieving 25-50mm optimal feed size for gravity separation
• Solution:Multi-cylinder Hydraulic Cone Crushers
  Liming Equipment:
  • HPT Series Cone Crusher (e.g. HPT400)
    • Laminated crushing preserves chromite crystal integrity
    • Automatic tramp iron release protects mantle
  • HST Series Cone Crusher (e.g. HST315)
    • ≤30mm product for friable Indian chromite

Stage 3: Tertiary Crushing (Optional) – Fines Control

• Challenge: Minimizing -1mm slimes for improved spiral recovery
• Solution:Fine Cone Crushers with precise CSS control
  Liming Equipment:
  • HPT500 Fine Cavity Cone Crusher
    • 8-15mm output for pelletized chromite
    • Hydraulic over-pressure protection

Integrated Auxiliary Systems

• S5X Vibrating Screen (e.g. S5X2460-3)
  • Polyurethane flip-flow screens for sticky ore
• B6X Belt Conveyor
  • Impact beds prevent chromite lump degradation

Technical Advantages of Liming Chrome Crushers

Configuration for Major Chrome Types

Performance Data (Turkey 400TPH Plant):

• Ore Type: Podiform chromite (UCS 250 MPa)
• Final Product: 85% 10-30mm (ideal for jig separation)
• Crusher Wear Rate: 0.8g/ton for HPT500 mantles

Why Choose Liming for Chrome Processing?
