Maximizing Flotation Yield: Low-Sliming Hydraulic Roller Crushing Solution for Spodumene Plants

Optimizing spodumene and lepidolite reduction by combating mineral over-crushing, eliminating iron contamination, and accelerating downstream ball milling performance.

Pillar A: Intergranular Bed Crushing (Anti-Sliming Control)

Our solution positions the heavy-duty Hydraulic Double Roller Crusher as the core fine-crushing vehicle. By replacing erratic hammer blows with massive, synchronized static hydraulic forces, the mineral crystals are compressed precisely down to a preset gap. Materials fracture cleanly along natural crystalline boundary interfaces, restricting the creation of fine mineral slimes (under 200 mesh) to below 10%, maximizing flotation yield.

Pillar B: Low-Wear Alloys (Flotation Purity Safeguard)

To avoid introducing mechanical iron that dampens reagent reactivity, the 2PGY series utilizes specialized low-RPM, high-torque operations alongside custom-formulated non-magnetic tungsten/chromium alloy roller liners. The low slip ratio ensures near-zero abrasive iron dust is introduced into the feed stream, maintaining clean mineral faces for prime collector-agent attachment.

Pillar C: Micro-Crack Genesis (Accelerated Ball Milling)

The intense spatial pressure applied within the dual-roller throat produces dense networks of sub-surface micro-cracks inside the cubic lithium particles. When these pre-stressed grains feed forward into primary wet ball mill steps, they shatter with significantly reduced resistance, cutting grinding times down by 25% and expanding liberation plant output capacity.
