Bunting® is the industry leader in magnetic separation equipment. Literally hundreds of thousands of our products are used in a variety of industries and manufacturing processes to protect your customer, equipment and brand from damaging tramp metal. Now, a select offering of our magnetic separation equipment is available at

Our separation technology is available in a variety of designs and options to fit any application. No matter where you use them, the result is the same: pure product, intact processing equipment and a solid reputation. A selection of in-stock Grate (Hopper) Magnets, Drawer Magnets, Plate Magnets and Magnetic Pulleys to catch ferrous materials are available online for immediate shipment. If you can’t find what you are looking for, need a custom size or a specific problem, e-mail our team at Bunting or Contact us for custom magnetic separators and custom magnetic separation applications.


Grate Magnets (Hopper Magnets) provide a properly configured, high-density magnetic field to trap and hold ferrous fines, fragments, and small metal objects as it passes through the stainless steel tubing. They can be installed – or simply laid – inside hoppers, housings, and bins – and easily removed for cleaning. Grates are built for low-abrasion applications and should measure at least twice the size of your outlet opening, so as not to restrict product flow. Grate Magnets (Hopper Magnets) are available with ceramic magnets or high intensity rare earth neodymium magnets, round or square, in a variety of sizes.

Plate Magnets are installed in enclosed flow lines easily and economically to remove ferrous fines as well as large pieces of tramp iron. Ideal applications for plate magnets are free-flowing or pneumatically conveyed powdery, moist, lumpy or abrasive products that might choke or cause rapid wear in cartridge-based separators. Plate Magnets can also be installed above conveyors or below conveyor drive pulleys to capture contaminants as material drops from open belts. Available with ceramic magnets or high intensity rare earth magnets in a variety of sizes. For very fine metal particles, we suggest rare earth magnets.

Bunting Drawer Magnets are the industry’s best for superior contaminant capture in gravity free-fall applications. With over 100,000 Bunting magnetic separation drawers in use today, these are the plastic industry’s most trusted, most used and most popular magnet to ensure product purity. Staggered rows of temperature-compensated, high intensity neodymium magnets instantly stop metal, purifying your product, before it enters your expensive extrusion, injection, or blow molding equipment. Bunting offers the most complete line of drawer magnets here. However, if you need a standard drawer magnet, choose a 6” square or 8” square and order today for immediately shipment.

Our Magnetic Head Pulleys (Pulley Separators or Magnetic Conveyor Pulleys) are an easy, reliable solution to separate ferrous from non-ferrous in your product stream. Used at the discharge end on belt conveyors, they provide maximum continuous protection against tramp iron in the processing of materials such as recycled products, chemicals, food and grain, plastics, coal and other mining. Easily installed, they require no maintenance or cleaning. The magnetic pulleys come standard with ceramic magnets; rare earth magnets are available upon request. Stainless steel shell construction. Pulleys are available in diameters of 6″, 8″, 10”, and 12″. Widths range from 14” to 38”. XT Hubs and Bushings are standard.
