Grate Magnets
Bunting® Grate Magnets provide a properly configured, high-density magnetic field to trap and hold ferrous fines, fragments, and small 
metal objects. Stainless steel tubing and frames are welded into strong, integral units. They can be installed – or simply laid – inside hoppers, housings, and bins – and easily removed for cleaning. Grates are built for low-abrasion applications and should measure at least twice the size of your outlet opening, so as not to restrict product flow.
Round, Square, and Rectangular Grates
Bunting® Hopper Magnets come in a variety of shapes and sizes for use in round, square, or rectangular hoppers, chutes, housings, and bins. They are ideal for trapping ferrous objects in free-flowing materials conveyed by gravity. Grates should have at least twice the cross-sectional area of the hopper outlet opening.
Standard units feature 1” diameter Bunting® Magnetic Cartridges encased in 304 stainless steel and mounted on 2” centers – with optional rod or angle baffles to help direct product flow over the cartridges. Standard grate dimensions range from 4” to 36”. We stock 4”, 6”, 8”, 10”, and 12” round and square grates with angular baffles and Ceramic loads. For more information, request Spec. Sheet #2010. * Stringer height – 2”

Ordering Information
Part numbers for grates describe physical features. The numbers have four parts. The first two letters indicate separator type and shape. The second part consists of digits that give dimensions in inches. Rectangular grates have both width and length specified. The third and fourth parts do not appear in the table. They specify baffles and magnetic material.
