Grate Magnets

Eriez grate magnets for removing metal. Model P grate shown.

Eriez Grate Magnets consist of one-inch diameter magnetic tubes in a grid formation designed to allow feed material to cascade through the grate, effectively spreading magnetic protection through the cross sectioned area of a pipe, chute or hopper. Ceramic and Rare Earth designs are available, as well as Easy To Clean and Automatic Clean Grate Magnets In Housings. Powerful, permanent magnetic protection against fine and tramp iron contamination. Designed for simple installation in steep-sloped hoppers, odd and irregular shaped hoppers, floor openings, vertical closed chutes, and ducts.

Standard Grate Magnets
For many years Eriez permanent magnet grates have used ceramic or Alnico magnet materials as their energy source. When built with Eriez–designed circuits, these separators provide good magnetic fields for a nominal cost and satisfactorily remove both tramp and fine iron contaminants in most applications. They continue to be the magnets most frequently used to improve the product purity of dry bulk materials

Xtreme® Rare Earth Grate Magnets
The Xtreme® RE separators available from Eriez remove weakly magnetic or very fine iron contaminants. They have more strength at a greater distance than conventional permanent magnets, higher gradients, and increased holding force. This means they can reach out and attract weakly magnetic or very fine iron contaminants and hold them so tightly that wipe-off by product flow is virtually eliminated.

Model P Grates Magnets

A versatile, powerful, magnet designed specially for odd shaped, round, oval or round cornered hoppers. The Model P has been constructed with a flexible basic design which makes it a real piece of protective magnetic equipment for virtually any shape hopper. In operation the sturdy grid bars positioned over the magnetic element act as baffles to deflect your flow of material onto the magnetic tubes where iron contamination is trapped and held. The built-in baffles control excessive speeds of material, but a smooth steady flow is not obstructed.

Model BA Grates

This separator provides “Final Magnetic Action” on bulk foods, chemicals, pharmaceuticals, etc. being packaged in barrels or similar type containers. These units are the result of many requests for a portable type magnetic separator for use in a final separating action as materials are being packed in barrels or other types of large containers.


Wing and Drawer Type Grates

Eriez Wing and Drawer grate magnets for hoppers and floor openings.

Double-bank units are designed to give double protection in installations where the problem of iron contamination is particularly acute. These models have a second row of magnetic tubes aligned directly below the open spaces between tubes in the top row.

Wing-type units can be quickly put to work in hoppers and floor openings. Adjustable wings add to ease of installation. No bolting is necessary, and units can be lifted out for easy cleaning.

Drawer-type Grates have been specifically designed for use in closed chutes and ducts. They come complete with handle and latches. These models are easily inspected and cleaned by sliding the “magnetic drawer” from an opening made inside of housing.


Eriez Easy-to-Clean Grate-In-Housing grate magnet. Shows two banks of magnets which you pull to clean.Easy-to-Clean Grate-In-Housing

The Easy-To-Clean Rare Earth Grate-In-Housing provides for the quick removal of accumulated fine iron contamination. Simply slide the individual door fronts from the housing and the accumulated metal contamination is scraped from the tube and discharged out the front of the housing. The cleaning cycle is reduced to only a few seconds with this push–pull operation.


Automatic Easy-to-Clean Grate-In-Housing

Eriez Automatic Easy-To-Clean Grate-In-Housing. Shown with tube magnets and pneumatic cylinders for auto clean.
Eriez Automatic Easy-to-Clean Model TGH-2 Drawer Grate In-Housing uses a powerful Rare Earth magnet circuit to provide superior separation performance on fine tramp metal contamination. Designed for push button operation, the Automatic Easy-to-Clean is ideal for applications where the process is stopped for grate magnet cleaning.


Rota-Grate® In-Housing

Rota-Grates In-Housings are ideal for dusty installations where an enclosed system is necessary. The slowly rotating tube circuit will catch unwanted or damaging tramp iron and prevent bridging of sticky or powdery materials like flour or corn starch.
