The Benefit Of Using Plate Magnets

Plate magnets are used industrially to remove fine iron and tramp iron from sugar, corn, flour, gravel, and granular plastic. These magnets are placed in chutes and above conveyor belts that transport the processed product. The plate magnet can be placed above the flow of product or below the flow of product to attract tramp iron like staples, bailing wire, or nail contaminants.


By removing tramp iron from mass produced food, the standards set by the Food and Drug Administration in the Manufactured Food Standards Program can be met. Food processing plants that utilized plate magnets in their production line protect the product’s purity, prevent damage to their machinery, and eliminate the potential hazards that could result from the inclusion of the tramp iron in their product.

The plate magnet has a superior strength-to-weight ratio, is constructed of sanitary stainless steel, and usually comes with a lengthy warranty. Many plate magnets are equipped with liquid tight face plates and can be built with a stepped face plate to better retain round tramp iron particles. The plate’s magnetic pull normally comes with a lifetime warranty.

Some chutes have self-cleaning magnets with stripper pan cleaning mechanisms that readily release the metal when activated, while others are installed on swing away structures for easy manual cleaning. Still others need to be unclamped and opened manually for the magnetized metal to be released.

Magnets come in several versions. Flush plate magnets are used for above-the-flow chute and belt applications. Exposed pole plate magnets are used for below-the-flow applications and are normally in low to medium volume production. Spout plate magnets are perfect for below-the-flow high volume applications. There is a plate magnet that will perfectly suit any processing application, so that production will remain free of contaminants. This is a job perfectly suited for the plate magnet and its multiple designs.
