Products Description
Need to remove ferrous contaminants from your product stream to ensure purity and protect equipment? Guanjiang's Magnetic Separators are specialized industrial devices designed to remove ferrous contaminants from various processing lines using high-intensity magnetic forces. Using powerful permanent magnets or electromagnets, they attract and separate magnetic particles from non-magnetic materials — ensuring product purity and protecting downstream equipment. Available in plate magnets, grate magnets, drum separators, and pipeline models, they capture ferrous particles as small as 30 microns from dry powders, granules, and liquid slurries.
Key Advantages
Removes Particles Down to 30μm
Captures ferrous particles as small as 30 microns. Prevents product contamination in food and pharmaceutical applications — maintains consistent product quality and purity.
Equipment Protection
Prevents damage to crushers, grinders, and other processing machinery. Reduces maintenance costs and downtime — extends equipment service life.
Continuous Operation
Continuous operation with minimal maintenance. Self-cleaning options available for automated processing. Low energy consumption compared to other separation methods.
Multiple Configurations
Plate / Grate / Drum / Pipeline models. Suitable for dry powders, granules, and liquid slurries. Customizable magnetic strength for specific applications.
Low Operational Costs
Low operational costs with high reliability. Reduced product loss from contamination — quick ROI through improved quality.
Permanent or Electromagnetic
No external power required for permanent magnet models. Rare earth (Neodymium) magnets for maximum strength.
GMP Compliant
Sanitary designs available — stainless steel construction, smooth surfaces for food and pharmaceutical use.

| Chemical Industry | Catalyst recovery, raw material quality control, process stream protection |
Frequently Asked Questions
Q1: What is the difference between permanent and electromagnetic separators?
A: Permanent magnets require no external power — lower operating cost, always "on." Ideal for continuous operation. Electromagnets can be switched on/off and offer adjustable field strength — higher initial cost but useful for batch processing where easy cleaning is needed (field collapses for magnetic particle release).
Q2: What magnetic strength is required for my application?
A: 3,500-5,000 Gauss: Standard tramp iron removal (general food/plastics). 6,000-8,000 Gauss: Fine powder applications (pharmaceuticals). 10,000+ Gauss (Neodymium): Weakly magnetic materials (stainless steel fines, fine iron oxides). Contact us with your particle size and material characteristics for a recommendation.
Q3: How do you clean the magnetic separator?
A: For manual models, slide out the magnet assembly, wipe captured metal from magnetic tubes/plates into a collection container. For self-cleaning models (automatic), captured metal is continuously or periodically discharged without stopping production. Sanitary designs feature smooth surfaces for easy wash-down in food/pharma environments.
Q4: Can the magnetic separator be used for food/pharmaceutical applications?
A: Yes. We offer sanitary designs with SS316L construction, electropolished surfaces, and smooth welds. Magnets are encapsulated in stainless steel, preventing product contact. Units meet FDA, GMP, and 3-A sanitary standards — suitable for direct food contact and pharmaceutical processing.
Q5: What is the maximum operating temperature?
A: Standard neodymium magnets operate up to 80°C. For high-temperature applications, we offer Samarium Cobalt (SmCo) magnets operating up to 250°C. Ceramic (ferrite) magnets handle up to 250°C but have lower field strength. Please specify your operating temperature when ordering.
