Magnetic Separators for Mineral Processing

Overview

Product Specifications

Types & Models:

Wet Drum Separators

Capacity: 0.5–180 t/h; shell diameter: 600–1500 mm; magnetic intensity: 800–8,000 Gauss.

Applications: Iron ore beneficiation, coal purification (e.g., CTB6012 model with 10–20 t/h capacity)

Dry Drum Separators:

Feed size: 0–6 mm; magnetic intensity: 1,000–6,000 Gauss (e.g., GCT-918 model with 900×1800 mm drum)

High-Intensity Roll Separators:

Field strength: up to 15,000 Gauss; capacity: 0.2–200 t/h (e.g., CGD240-1800-1600 model for rare earth minerals)

Key Metrics:

Power Consumption: 0.37–15 kW (varies with size and intensity) 

Material: Stainless steel drums with epoxy or Ni coatings for corrosion resistance

Product Grades

Standard Grade: For general iron ore separation (e.g., CTB series wet separators)

High-Performance Grade: Precision separators for rare earth minerals (e.g., three-disc dry separators with 20,000 Gauss) 

Industrial Grade: Ruggedized designs for harsh environments (e.g., self-cleaning overband separators)

Applications

Mining: Recovery of magnetite/hematite from tailings; pre-concentration of low-grade ores

Recycling: Removal of tramp iron from scrap metal or e-waste 

Ceramics/Food: Purification of non-metallic materials (e.g., quartz sand) 

Steel Industry: Slag processing and mill scale recovery 

FAQs

How to choose between wet and dry separators?

Wet types suit slurries (<3mm particles); dry types handle powders or bulk materials 

Maintenance requirements?

Regular cleaning of magnets and inspection of belts/drums; self-cleaning models reduce downtime.

Can separators handle high temperatures?

Oil-cooled electromagnets operate up to 150°C; standard models tolerate ≤80°C

Field strength vs. efficiency?

Higher Gauss improves fine particle recovery but increases energy costs

Customization lead time?

Typically 10–30 days for tailored designs (e.g., drum size adjustments)
