Lithium Ore Crusher

Precision Crushing for Lithium Battery Raw Materials

With surging demand for battery-grade lithium, efficient liberation of spodumene (LiAlSi₂O₆) and lepidolite from hard pegmatite ores (UCS 150-250 MPa) is critical. Liming Heavy Industry designs Lithium Ore Crusher that minimize fines generation – preserving +0.3mm particles vital for dense media separation (DMS).

Stage 1: Primary Crushing – Pegmatite Reduction

• Challenge: Breaking coarse-crystalline ore (≤600mm) with low iron contamination
• Solution:Jaw Crusher with ceramic-lined crushing chambers
  Liming Equipment:
  • C6X Series Jaw Crusher (e.g. C6X125)
    • ≤430mm feed size for Australian Greenbushes-type ore
    • 316L stainless steel frame for corrosive environments
  • PE Series Jaw Crusher (e.g. PE900×1200)
    • ≤180mm output with <3% -10mm fines

Stage 2: Secondary Crushing – Selective Liberation

• Challenge: Preserving coarse spodumene crystals (1-20mm) for DMS
• Solution:Single Cylinder Cone Crusher with inter-particle crushing
  Liming Equipment:
  • HST Series Cone Crusher (e.g. HST250)
    • ≤25mm product with cubicle shape
    • 30% lower fines vs multi-cylinder designs
  • HPT Series Cone Crusher (e.g. HPT300 Fine Cavity)
    • 8-12mm output for flotation feed

Stage 3: Tertiary Crushing – Fines Control

• Challenge: Minimizing slimes in lepidolite clays
• Solution:Vertical Shaft Impact Crusher with grinding path control
  Liming Equipment:
  • VSI6X Sand Maker (e.g. VSI6X1263)
    • Rotor speed adjustable 900-1500 rpm
    • -0.075mm generation <15%

Integrated Classification Systems

• S5X Vibrating Screen (e.g. S5X1860-3)
  • Polyurethane screens for 0.3/1/3mm cut points
• LUM Ultrafine Mill (Optional for clay-rich ores)

Technical Advantages for Lithium Applications

Plant Configuration for Lithium Ore Types

Performance Data (Zimbabwe 300TPH Plant):

• Ore: Petalite-spodumene blend (UCS 180 MPa)
• Product: 92% 0.3-6mm (ideal for DMS)
• Fe Contamination: ≤0.008%

Why Global Lithium Miners Choose Liming

“Over-crushing spodumene reduces DMS recovery by 20-35% – our HST crushers preserve critical +0.3mm fraction.”
