Lithium Battery Material Iron Removal Equipment

Product Overview

Lithium-ion battery material de-ironing equipment is designed for high-precision removal of magnetic impurities from battery-grade materials. As iron contamination directly impacts battery energy density, cycle life, and safety—potentially causing internal micro-short circuits and thermal runaway—this equipment delivers critical purity control for modern lithium battery production . Available in both dry powder and wet slurry configurations, these systems can reduce iron content to sub-0.001% (ppm to ppb level) to meet the stringent quality requirements of the energy storage sector .

Core Advantages

• High-Gradient Electromagnetic Field: Achieves magnetic strength up to 19,500 Gauss, effectively capturing fine ferromagnetic and weak magnetic particles down to micron and submicron levels

• Dual Configuration Options: Available for dry powder processing (cathode/anode materials, precursors) and wet slurry applications (electrolytes, precursor slurries) to cover the full lithium battery material production chain

• Fully Automatic Operation: PLC-controlled system with HMI touchscreen automatically executes feeding, excitation, separation, and iron discharge cycles—enables one-person, multi-machine management

• Superior Cooling Technology: Oil-water复合冷却 (oil-immersed sealed coils with external heat exchangers) ensures low temperature rise and extended coil service life exceeding 10 years

• Contamination-Free Construction: Wetted parts utilize 316L stainless steel and specialized coatings (PTFE, wear-resistant materials) to prevent secondary contamination of sensitive battery materials

• Sealed & Dustproof Design: Fully enclosed material passages solve dust pollution issues, ensuring clean production environments for battery-grade applications

• Industrial-Grade Reliability: Forced oil circulation cooling systems and robust construction support 24/7 continuous operation with remote monitoring capabilities via Ethernet
