Slurry Electromagnetic Separator

      The equipment employs high-gradient magnetic separation (HGMS) technology. When the excitation coil is energized, a high-intensity, high-gradient magnetic field is generated within the separation chamber. The slurry flows through the magnetic field region under pump-driven or gravitational action; ferromagnetic particles in the slurry are strongly adsorbed and retained by the high-gradient magnetic medium, while the clean, non-magnetic slurry passes smoothly through the chamber and is discharged. The device is equipped with a fully automatic PLC control system: once the adsorption reaches the set time or flow rate, the system automatically stops feed, de-energizes or reverses the magnetic field (some models are paired with high-pressure water/air backflushing), thoroughly flushing away the iron contaminants adhered to the magnetic medium, and then automatically resumes magnetization and feeding, enabling 24-hour continuous operation.

Features and Advantages

• Ultra-high iron removal accuracy: Magnetic field strength up to 20,000 GS or higher, effectively removing micrometer-sized ferromagnetic contaminants with an iron removal rate exceeding 99.5%.
• Fully automatic intelligent control: The PLC intelligent system supports automatic magnetization, automatic cleaning, and automatic discharge, reducing manual intervention and ensuring more stable operation.
• Efficient heat dissipation for stable operation: Utilizing forced oil circulation or water-cooling heat dissipation, the magnetic field remains stable, allowing the equipment to run continuously over long periods.
• Hygienic-grade stainless steel construction: The material-contact parts are made of 304/316L stainless steel, offering corrosion resistance and easy cleaning, suitable for the food, pharmaceutical, and lithium-battery industries.
• Reduced material loss: Optimized iron discharge and rinsing mechanisms minimize slurry carryover, thereby reducing waste of high-value materials.

Optional Configurations

• Magnetic field strength up to 20,000 GS or higher, effectively removing micrometer-sized ferromagnetic contaminants with an iron removal rate exceeding 99.5%.
