Industrial Magnetics Inc. (IMI), Boyne City, MI, has been in business since 1961. In the mid-1970s, the company began marketing its purification and protection magnets to the milling industry. Milling product lines. Director of Field Sales/Marketing Dennis O’Leary says IMI currently offers three primary product lines for use in the milling industry: plate, gratestyle/gravity flow, and pneumatic line. Plate Magnets “All of IMI’s plate magnets can be provided with engineered chutes to fit directly into the mill’s processing lines,” O’Leary says. Flush face. This style of plate magnet is designed for above-the-flow applications. This model is available in ceramic and rare earth. Exposed pole. This style is designed for above- or below-the-flow applications. Exposed pole models are ideal for lowvolume chute installations with either ceramic or rare earth magnetic circuits. Spout style. The spout style plate mag- IMI’s large tube-in-housing model (left) features three-inch-diameter rare earth tubes. The exposed pole plate magnet (right) is available in rare earth and ceramic. nets feature dual diverters and an exposed pole to provide maximum tramp metal separation and superior wash-off protection for high-volume, below-the-chute applications. Grate Style and Gravity Flow Due to the flow properties of flour, O’Leary says IMI’s grate and gravity flow magnets are popular choices in the milling industry. Round tube magnetic grate assembly. These are ideal for ferrous metal separation in bins, chutes, drawers, bag dumps, and hoppers. EZ-clean/self-clean drawer in housing. This style is ideal for ferrous metal separation in a wide variety of dry processing ap- plications. A large tube housing incorporates three-inch-diameter rare earth tubes in the drawer-in-housing configuration. Drum separator. This model is a continuously self-cleaning unit that removes ferrous metal contamination. Pneumatic Line Exposed pole tube and bullet magnets. These types feature the magnetic circuit built into the body of the housing. The ceramic version is ideal for capturing large pieces of tramp metal, while the rare earth models capture fine metallic particles. Contact info.

Crawshaw says Puritan provides a variety of magnetic separators for the milling industry. Plate Magnets Installed on the bottom side of a chute, a plate magnet will provide maximum protection as product travels through the magnetic circuit. “The magnetic field projects from the face of the plate magnet, reaches into the product stream, and pulls the ferrous contaminants to the magnet face,” Crawshaw says. To prevent captured ferrous contaminants from being washed off by oncoming product, Crawshaw says a trap face plate magnet should be installed. Grate Magnets Grate magnets are placed directly in the product stream, allowing free-flowing products to come in direct contact with the grate. While typical grate magnets are constructed with one-inch-diameter magnetic tubes mounted on two-inch centers in a frame, Crawshaw says Puritan can manufacture the length and width to any dimension. Drawer Magnets Drawer magnets operate much like grate magnets with a few differences. Crawshaw notes that with a drawer magnet, multiple staggered rows can be layered on top of each other. With Puritan’s EZ CLEAN drawer magnet, Crawshaw says cleaning the magnetic surface is as easy as pulling out the drawer. Vertical Spout Magnets “These magnets are engineered to remove fine to large ferrous contaminants from high-volume, gravity-fed product streams,” Crawshaw says. As the product enters the housing, Crawshaw says two plate magnets pull contaminants from the separate product With Puritan’s vertical spout magnet, contaminants are pulled from dual product streams using opposing magnets. streams. The magnetic separator is cleaned by releasing the drawer latches and removing the internal drawer assembly. Air-Vey Magnets Crawshaw says Puritan’s Air-Vey magnets are designed to remove ferrous contaminants from products in pneumatic conveying systems operating at 15 psi or less. “The Air-Vey magnets install easily in a horizontal, vertical, or angled position,” Crawshaw says.
