Tungsten Ore Crusher

Tungsten Ore Crushing Challenges

Tungsten ores (wolframite (Fe,Mn)WO₄ / scheelite CaWO₄) require:

• Selective liberation at 2-10mm for gravity separation
• Minimizing slimes (-0.075mm) causing >15% WO₃ loss
• Handling abrasive quartz veins (UCS 250-350 MPa)

Liming Heavy Industry designs Tungsten Ore Crushers with precision closed-side settings (CSS) for complex vein deposits.

Stage 1: Primary Crushing – Vein Ore Reduction

• Challenge: Breaking hard quartz-wolframite masses
• Solution:Jaw Crushers with reinforced toggle system
  Liming Equipment:
  • C6X Series Jaw Crusher (e.g. C6X110)
    • ≤425mm feed for Chinese wolframite ore
    • MX14 jaw plates with 2,800+ hours lifespan
  • PE Series Jaw Crusher (e.g. PE750×1060)
    • ≤100mm output with <5% -3mm fines

Stage 2: Secondary Crushing – Selective Liberation

• Challenge: Preserving scheelite crystals (1-5mm)
• Solution:Multi-cylinder Cone Crushers
  Liming Equipment:
  • HPT Series Cone Crusher (e.g. HPT200 Fine Cavity)
    • Laminated crushing reduces slimes
    • 5-15mm adjustable output
  • HST Series Cone Crusher (e.g. HST160)
    • ≤12mm for scheelite skarn ores

Stage 3: Tertiary Crushing – Gravity Feed Prep

• Challenge: Generating 2-5mm jig/spiral feed
• Solution:Vertical Shaft Impact Crushers
  Liming Equipment:
  • VSI6X Sand Maker (e.g. VSI6X1150)
    • Rotor speed 1,200-1,800 rpm
    • -0.075mm generation <10%
  • LUM Ultrafine Mill (For tailings reprocessing)

Critical Auxiliary Systems

• S5X High-Frequency Screen (e.g. S5X1545-2)
  • 0.5/1/2mm polyurethane decks
• B6X Dust-Proof Conveyor
  • Sealed design for WO₃ dust containment

Technical Advantages for Tungsten Ores

Plant Configuration (Bolivia 180TPH Project)

Performance Data:

• Ore: Wolframite-quartz vein (WO₃ 0.8%)
• Final Product: 91% 1-6mm
• WO₃ Recovery Increase: 22% vs conventional crushing

Why Tungsten Miners Choose Liming

“Overgrinding reduces wolframite recovery by 30% – our HPT fine cavity maintains >90% +0.5mm fraction.”
