What is The Magnetic Filter and What Do They Do?
A Magnetic Filter is a device used for filtering and sorting, which employs magnetic force to capture fine iron impurities within fluids and semi-fluids. It’s typically mounted inside or outside of hoppers, discharge ports, or transportation pipelines. As materials pass through the magnetic filter, iron impurities are strongly adhered to the magnetic surface, effectively purifying the material and safeguarding downstream equipment.
Magnetic Filters have a wide range of applications and are especially effective for filtering fine iron impurities in powders, particles, liquids, and gases. The most common types of magnetic filters include:
Tube Magnets: Strong magnets sealed in a stainless steel tube form a high-density magnetic field circuit, capturing ferromagnetic substances in mud and powder. They are capable of absorbing nano-level particles with a magnetic intensity of over 12000 Gauss.
Grate Magnets (Magnetic Grids): These are placed in storage, drawer boxes, hoppers, etc., to catch and remove iron filings, pieces, and other metallic substances from product flow. Grate Magnets consist of several tube magnets arranged in a stainless steel frame, which can be square or round to match the pipeline shape.
Drawer Magnets: Essentially multi-layer grate magnets with a housing, drawer magnets are used across various industries to remove ferromagnetic impurities from dry powders, sheets, granular materials, etc. Pneumatic self-cleaning models are also available for continuous automatic iron removal.
Magnetic Liquid Traps (Magnetic Liquid Filters): These are used to remove iron impurities and ferromagnetic particles from fluids, semi-fluids, and other materials with varying viscosities. Magnetic liquid traps have magnetic tubes fixed on a detachable device, ensuring that iron impurities are captured as the liquid flows through.
In summary, magnetic filters play a crucial role in industrial applications by effectively removing ferrous contaminants from liquids, powders, and granular materials. They enhance product quality, protect equipment, improve process efficiency, and promote environmental sustainability. By incorporating magnetic filters into their filtration systems, industries can ensure cleaner and safer end products while optimizing their operations.
