Grate Magnets

Square Grate Magnets

Grate(5)

Grate Magnets are placed directly in the product stream allowing free flowing products to come in direct contact with the grate. Grate Magnets are typically constructed with one inch diameter magnetic tubes mounted on two inch centers in a frame. The length and width can be fabricated to any dimension, usually in two inch increments.

Grate Magnets offer excellent protection from metal contamination. As product flows over the magnetic tubes, captured metal contaminants are pushed to the underside of the tube where they are now out of contact with the product flow preventing washoff back in to the clean material.

Cleaning is achieved by removing the Grate Magnet and wiping the magnetic tubes clean. It is important to keep in mind that by placing a Grate Magnet in the product flow, you will be reducing fifty percent of your flow through area. Grate Magnets should be sized so they do not impede the flow of product.

Magnetically engineered to provide a full range of ferrous metal separation from free-flowing products with gravity fall processing applications. Puritan's designs offer maximum capture, control and protection of equipment while improving product purity. For maximum protection, locate in critical areas where capture is possible, most needed, and where removal for cleaning is feasable. Grates are most effective when the product is dry, free flowing and does not bridge between the magnetic tubes (Puritan also offers other magnetic designs for those more difficult applications). Select a Magnetic Grate at least twice the cross sectional area of the incoming spout opening and discharge. When in doubt, phone Puritan for engineering assistance.
