I. The Critical Need for Purity in New Energy
The Challenge: Minute ferrous impurities (iron particles, shavings) in battery materials like cathode powders (NMC, LFP, LCO), anode materials, lithium concentrates (spodumene), and electrolyte precursors can severely degrade electrochemical performance, cause safety hazards (internal shorts, thermal runaway), and lead to costly batch rejections.
Hengji’s Mission: To provide robust, reliable, and highly effective magnetic separation solutions specifically tailored to the unique particle size, flow characteristics, and sensitivity of new energy materials.
II. Targeted Solutions for Key Production Stages
Hengji offers a portfolio optimized for the stringent demands of lithium battery and new energy material manufacturing:
1.Ultra-Fine Dry Powder Purification:
oSolution: High-Intensity Roll Magnetic Separators (CTQ Series).
oApplication: Continuous, automated removal of ferrous contaminants from sensitive cathode and anode powders (e.g., NMC, LFP, LCO, graphite) during processing and before cell assembly.
oImpact: Ensures exceptional purity of the active materials, maximizing energy density, cycle life, and safety of the final battery cell. Handles µm-sized powders efficiently with precise control.
2.Slurry & Liquid Stream Protection:
oSolution: Pipeline Magnetic Separators.
oApplication: In-line purification of slurry streams containing electrode materials or liquid precursors (e.g., electrolyte components) within closed pipeline systems.
oImpact: Prevents ferrous particles from contaminating sensitive slurries or liquids, protecting downstream coating equipment, mixers, and ensuring the integrity of the final coated electrodes or electrolyte formulation. Stainless steel construction ensures compatibility.
3.Raw Lithium Concentrate & Mineral Upgrading:
oSolution: High-Gradient Magnetic Separators (GTC Series).
oApplication: Pre-concentration and purification of weakly magnetic lithium-bearing minerals (e.g., spodumene) and other critical raw materials (e.g., manganese ores) prior to chemical processing.
oImpact: Effectively removes fine iron-bearing gangue minerals, improving the feed grade for hydrometallurgical processing, reducing acid consumption, waste generation, and overall production costs. Solves clogging issues common with fine particles.
