In-Line Magnets

In-Line Magnets for Gravity or Pneumatic Systems

Bunting’s in-line magnets offer effective, high strength magnetic separation that is easy to install and integrate with your existing systems. Bunting’s design has no maintenance required aside from cleaning the ferrous metal contamination it captures. The design of Bunting’s in-line magnetic separation equipment features full-flow architecture that leaves the product stream unobstructed. In-line magnets are suitable for a diverse range of industries, including food, grain and milling, powder and bulk, plastics, and recycling.

In-Line Magnets – Technical Specifications

Bunting offers gravity, pneumatic, and center-flow in-line magnetic separation equipment. As material flows across the surface of a powerful rare earth magnet, the magnetic force captures and traps ferrous metal contamination, holding it against the face of the magnet to prevent it from re-entering the product stream. In gravity and pneumatic in-line magnets, tapered transitions guide material directly over the face of a hinged plate magnet, which swings away from the housing to enable quick external cleaning. In center-flow in-line magnets, the magnet achieves optimal contact with the product flow by suspending a conical magnet in the center-line of the housing. All of our designs can come with 10,000 gauss to comply with food standard.

To deliver powerful magnetic separation, our in-line magnetic separation equipment comes standard with rare earth magnets, although we do offer other options based on your needs. For optimum safety, metal-detectable gaskets and grommets are standard in the housing of in-line magnets. All of our pneumatic units come with a lock out tag out feature, allowing operators to lock the unit in order to prevent injury or tampering from personnel. All of our pneumatic units come with a sensor backplate, so operators can install a sensor to tell them when the magnet is open or when the magnet was last cleaned. This helps operators know if it is safe to run their product, or if maintenance is keeping up with cleaning. Our in-line magnets excel at removing ferrous fines as well as larger pieces of tramp metal contamination from your material, and extensive customization options are available. Additionally, Bunting’s units are designed to prevent the product from degradation and do not cause it to splinter.

Pneumatic In-Line Magnets

Pneumatic in-line magnets are built for use in dilute phase pneumatic conveying systems. They can be installed easily with optional factory-supplied compression couplings, and work best in horizontal runs with the plate magnet down to take advantage of material stratification. Pneumatic in-line magnets feature full-flow architecture to allow an unobstructed product stream.

Features Include:

• Designed for unobstructed product flow in dilute phase conveying up to 15 psi.

• Best suited for horizontal installation, portable cart available. Compression couplings speed in-line installation.

• Best suited for horizontal installation. Portable cart available.

• High-energy rare earth tapered step plate magnets are standard.

• Tapered transitions guide material directly over the face of the hinged plate magnet, which swings away from the housing for quick external cleaning.

• Tapered step plate magnet helps prevent wash off of trapped metal by product flow.

• Food, sanitary, and USDA finishes available to fit your production safety regulations.

Ideal for applications in the Plastics, Recycling, Powder & Bulk, Grain & Milling and Food Industries

Center-Flow In-Line Magnets

Center-flow in-line magnetic separators are engineered to remove ferrous fine particles and larger pieces of tramp iron from dry particulates as they travel through dilute-phase pneumatic conveying lines. To achieve optimum contact with the product flow, a conical magnet is suspended in the center-line of the housing. This tapered, exposed-pole cartridge has a stainless steel “nose cone” to direct the flow of materials around the magnet. The magnet’s tapered poles allow ferrous fine particles to collect out of the direct air stream. Additionally, the trailing end of the magnet is an active pole which will collect any tramp metal that gets swept down the cartridge. The magnet’s shell is designed to give long magnetic exposure to dry powders in order to ensure your product achieves maximum magnetic separation.

Features Include:

• Designed for unobstructed product flow in dilute phase conveying up to 15 psi.

• Available with all line and fitting types. Placement in vertical run makes optimum use of the magnetic field and ensures maximum efficiency in separation.

• High-energy rare earth magnets are standard.

• Optional clear view inspection port to observe separation process.

• Comes standard with a tapered step face to prevent product wipe off.

• 3” and 4” models are manufactured using new bolt-on flange design for quick delivery.

Ideal for applications in the Food, Grain & Milling and Powder & Bulk Industries

Gravity In-Line Magnets

These magnets allow you to utilize our powerful plate magnets in round, sloping spouting where material is under gravity flow. For effective tramp capture, spouting should be angled no more than 60° from horizontal. These units are perfect for applications that are tight on space.

Features Include:

• Tapered step magnet, effective for capturing material under gravity flow in round, sloping spouting.

• Food, sanitary, and USDA finishes available to fit your production safety regulations.

• Built to fit most gravity flow line sizes, allowing for a seamless fit into your operations.
