Wet Magnetic Drum Separator

Low-intensity magnetic separators designed for separating ferromagnetic and highly paramagnetic materials.
Commonly used in mineral processing for concentrating magnetite and similar minerals.

Functions in Dense-Medium Circuits :

• Medium recovery
• Medium cleaning
• Liquid rejection

Selection Parameters :

• Volume of rinse water
• Percentage of solids in slurry
• Percentage of magnetic material
• Required efficiency
• Required purity and solids content

Additional Information :

• Magnetite is the primary mineral separated
• Hematite and siderite can be processed after roasting
• Permanent magnetic drums are widely used in modern plants
• High solids discharge improves efficiency

Working Principle

• Material is fed onto a rotating drum containing a stationary magnetic circuit.
• Ferromagnetic particles are attracted to the drum surface and carried out of the non-magnetic stream.
• Non-magnetic material follows its natural trajectory and is discharged separately.
• Magnetic material is released once it exits the magnetic field.

• Iron ore processing (magnetite concentration)
• Mineral beneficiation
• Dense-medium separation circuits
• Coal processing

Magnetic field strength :

• Less than ~0.3 Tesla
• Typical: 0.12 Tesla at 50 mm from drum surface

Particle size handling :

• 0–6 mm (concurrent type)
• 0.6–6 mm (counter-current type)
• 0–0.5 mm (counter-rotation type, especially 0–0.15 mm)

• Permanent magnetic drum design
• Self-cleaning operation
• High-strength magnetic field
• Continuous separation process
• Suitable for high magnetic content materials
• Various magnetic circuit designs available:
• Standard axial
• High-gradient axial
• Interpole
• Salient pole
• Radial pole
• Criss-cross
