water-cooled electromagnetic slurry automatic magnetic separator, metal ore roughing and non-metal ore purification device.

Structure and Key Components
Magnetic System:
Permanent Magnet Type: Uses neodymium iron boron (NdFeB) or ferrite magnets with a field strength of 5,000–12,000 Gauss. No external power required, corrosion-resistant.
Electromagnetic Type: Generates adjustable fields (up to 20,000 Gauss) via energized coils, ideal for high-precision separation.
Magnetic Media:
Magnetic Rod Arrays: Parallel rods create dense magnetic zones for low-concentration, fine-particle slurries.
Magnetic Drums: Rotating drums with scrapers or reverse flushing for high-flow slurries.
Magnetic Grids: Mesh-like grids intercept large iron particles, often used as pre-filters in pipelines.
Chamber and Seals: Stainless steel (grades 304/316L) or engineering plastics (PP, PVDF) ensure corrosion and wear resistance, with sealed flanges to prevent leaks.
Cleaning Systems:
Manual Cleaning: Post-shutdown rod removal or manual cleaning via access ports.
Automatic Cleaning: PLC-controlled high-pressure spray, pneumatic scrapers, or demagnetization for uninterrupted operation.
Auxiliary Systems: Flow meters, pressure sensors, and alarms monitor slurry velocity and contamination levels.

Key Applications
Ceramics: Removes iron from clay and glazes to prevent black spots or discoloration after firing.
Mining & Mineral Processing: Separates magnetic minerals (e.g., magnetite) or removes iron from tailings to upgrade ore quality.
Lithium Battery Materials: Purifies cathode material slurries (e.g., lithium iron phosphate) to avoid iron-induced battery degradation.
Water Treatment: Removes magnetic suspended solids to protect filtration membranes.
Food & Pharmaceuticals: Filters metal particles from juices and medicinal liquids for safety compliance.
Chemicals & Coatings: Eliminates iron rust from pigments and resin slurries for uniform color quality.
