Q1: How is magnetic stability maintained during 24-hour operation?
By integrating active forced-oil cooling with constant-current PID regulation, we maintain magnetic flux variance within <1.5%.
Q2: Why is peak field induction based on FEA simulation?
Standard probes cannot fit into microscopic gradient zones. FEA is the globally recognized method for validating sub-micron capture force.
Q3: How does the “Automatic Capture-Purge” cycle improve efficiency?
The PLC system automates valve sequences for feeding and flushing, ensuring zero-downtime cleaning and consistent high-purity output.
Q4: Can this system handle highly viscous battery slurries?
Yes. The MAG SPRING series is optimized for conductive slurries and pastes with viscosities up to 10,000 mPa·s.
Q5: What is the expected service life of the electromagnetic coils?
With H-Class insulation and stable thermal control, coils are designed for a service life of 10-15 years under industrial conditions.

As a professional provider of industrial purification solutions, MAG SPRING offers advanced wet-type electromagnetic separators designed for the most demanding slurry de-ironing processes. Utilizing High-Gradient Magnetic Separator (HGMS) technology, our systems generate a high-intensity magnetic field up to 2.4T, ensuring the effective capture of micron-level ferrous impurities in high-viscosity fluids.
Our automatic slurry magnetic separators are the industry standard for battery material purification, specifically optimized for NCM/LFP cathode materials, Lithium Carbonate, and CNT dispersions. By integrating active oil-cooling systems and PLC-controlled automatic cleaning, we help manufacturers achieve PPB-level material purity while maintaining 24/7 operational stability in ceramic glaze, kaolin, and specialty chemical industries.
Q: What is the maximum slurry viscosity handled by the MAG SPRING system?
Our high-gradient matrix design is engineered for fluids up to 10,000 mPa·s, making it ideal for high-solid content battery slurries and thick ceramic glazes.
Q: How does the oil-cooling system impact magnetic field consistency?
The forced oil-cooling system ensures precise thermal management. By preventing coil overheating, we keep magnetic flux variance under 1.5% during continuous industrial operation.
Q: Why is HGMS (High Gradient) essential for micron-level iron removal?
HGMS creates concentrated localized magnetic gradients at the edges of the matrix media, providing the extreme capture force needed to trap sub-micron paramagnetic contaminants.
