Plate Magnets

Ramped Pole Plate Magnet

The most common application of the plate magnet is the ramped pole plate design. This magnetic separator is installed on the underside of chutes, typically with an incline of 30 to 60 degrees. As burden flows over the separator, it is briefly suspended in free fall by the ramp. The pole intensifier, strategically located at this point, then quickly pulls the tramp material out of the flow of burden. This combination is very effective for separation in high volume applications (provided that the burden depth is not too high) and is employed in the hump magnet, hammermill magnet, and chute separator designs. MSI’s FREE TESTING allows our customers to make informed decisions and purchase with confidence.

Hump Magnet

The hump magnet is a series of two plate magnets placed into a housing on the underside of the product flow. The product enters the housing, cascades over the first plate magnet, then is “flipped” and flows over the second plate magnet. This design exposes the tramp metal to a magnetic pickup zone even in high-volume applications, due to the placement of the magnets in the housing.

Cleaning hump magnets is easy. The magnets are hinged on one side, so they swing open and wipe off. The magnets can also have a stripper faceplate, which allows for EZ-Clean or self-cleaning designs.

Hammermill Magnet

The “hammermill” magnet gets its name from the most common piece of equipment it is used to protect, and is essentially one half of a hump magnet. These are employed not only in the protection of hammermills, but also any downstream equipment that has a moderate burden depth or where a hump magnet is not practical (e.g. limited vertical space).

Magnetic Chute Separators

For the least amount of flow restriction possible, MSI offers the magnetic chute separator. As its name suggests, it is essentially a continuation of the existing chute, and even comes in configurations that have no restrictions whatsoever. Magnetic chute separators are employed in vertical drops and have powerful magnetic elements on each side. As the burden flows down, the tramp material is pulled out. Like drawer magnets, these are available in manual clean, EZ-Clean, and self-cleaning styles. For larger openings, a wedge can be used in the center position.

Simple Plate Magnet

The simple plate magnet is typically installed over burdens and works by pulling tramp material out of the flow. These magnets can act in the same manner as a suspended magnet over small belts, or likewise in chutes that have low burden heights.
