Magnetic Separation Equipment

You will find Bunting Magnetics magnetic separation equipment in a wide variety of industries and manufacturing processes: Food, feed and grain; powder and bulk products; pharmaceuticals; chemicals; plastics; and recycling. Now, our magnetic separators are also available on BuyMagnets.com.
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. Bunting Magnetics provides Grate (Hopper) Magnets, Drawer Magnets and Plate Magnets to catch ferrous materials where you need them to!
Grate 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.
Plate Magnets install easily in enclosed flow lines to remove ferrous fines, as well as large pieces of tramp iron, from many types of free-flowing and pneumatically conveyed material. They can handle powdery, moist, lumpy, and abrasive products and large debris that might choke, bridge, 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.
Drawer Magnets are used to extract ferrous materials from non-magnetic materials. The Bunting “Just-In-Time” FFV Vacuum Drawer Magnet systems dry the resin at a central point and then convey small amounts of it to the molding machine. Bunting® Drawer Magnets have been the Plastics Industry’s most popular choice for extrusion, injection and blow molding equipment for over 40 years. Our FF series come standard with Neodymium Rare Earth Magnets powerful enough to capture and hold ferrous particles so small they might not be visible to the naked eye. Neodymium magnets have exceptional surface holding force for more complete removal of contaminants and less chance of “wipe-off”. FFV Drawer Magnets mount on the throat of the plastic molding machine and are equipped with an O-Ring seal at the drawer front to prevent air leaks. FFV Drawer Magnets are manufactured to withstand pressures up to15 in-hg without leaking. The drawer front is 1/2” thick, clear polycarbonate for strength and easy monitoring of the resin flow and tramp metal collection. The powerful magnetic cartridges can be pulled out of the housing for easy cleaning. Top and bottom flanges are built to your requirements.
These magnetic separation magnets are only the beginning. Bunting specializes in custom magnetic separators and custom magnetic separation applications.
