Magnetic Separator

About Magnetic Separator

 What is a Magnetic Separator?

A Magnetic Separator is a filtration device used to remove ferrous particles (iron, steel, etc.) from process fluids such as coolant, oil, or emulsions. It works by attracting ferromagnetic contaminants using strong magnets, improving fluid quality and protecting downstream equipment.

TYPES OF MAGNETIC SEPARATORS

1. Drum Type Magnetic SeparatorRotating drum with permanent magnetsCommon in coolant filtration systems
2. Roller Type Magnetic SeparatorMultiple rotating rollers for high-efficiency separationSuited for high-contamination environments
3. Candle Type Magnetic SeparatorVertical or horizontal housing with magnetic rodsCompact design for finer filtration
4. Overband Magnetic SeparatorMounted over conveyors to remove ferrous tramp
5. Drawer or Grill TypeManual cleaning, used in dry bulk materials

CONSTRUCTION & WORKING (Drum Type as example)

Components:

• Magnetic drum (rotating)
• Housing with inlet and outlet
• Scraper blade
• Coolant tank integration
• Optional gear motor

 Working Principle:

1. Contaminated fluid enters the magnetic separator.
2. Ferrous particles are attracted to the rotating drum surface.
3. As the drum rotates, clean fluid flows out.
4. A scraper removes ferrous sludge from the drum into a sludge box.
