Click here for more technical information about Bunting Magnets

Heavy Duty Hopper Magnets

Bunting grate style Hopper Magnets come in a variety of shapes and sizes for use in round, square, or rectangular hoppers, chutes, housings, and bins.  They are an effective way to remove ferrous metal and fragment contamination in free-flowing materials conveyed by gravity. This magnetic design provides up to 100% more active contaminant collection area than other designs. Buy the best hopper magnets.

Each cartridge is manufactured from tough #304 stainless steel and filled with high-density Ceramic 5 permanent magnet material. The Hopper Magnet features all stainless steel, welded construction with optional rod and angle baffles positioned between cartridges to direct the product flow over the magnet (plain style, with no baffles, is also available). Grates should have at least twice the cross-sectional area of the hopper outlet opening.

Torpedo Magnets

Bunting Torpedo Magnets are designed to be used in Just-In-Time (JIT) hopper loaders and are the best alternative to drawer magnets available.

The Torpedo Magnet consists of a formed stainless steel ring, welded to a high-energy rare earth magnetic cartridge, allowing the magnetic cartridge to hang suspended in the center of the JIT loader's glass tube. With the Torpedo Magnet in this position, tramp metal is captured before it can reach your plastic molding machine.

The bottom of the Torpedo Magnet is a live magnetic pole that allows tramp metal to collect and hide, preventing tramp metal wipe-off back into the product stream. The magnet can be inspected for tramp metal buildup by looking through the glass tube. The magnet can be removed and cleaned as required. The material level sensor, which is typically mounted on the outside of the JIT loader's glass tube, will not be affected by the Torpedo Magnet.

Torpedo Magnets are available in either 1" or 5/8" diameter high-energy rare earth magnetic cartridge designs. Four sizes are available to fit most Just-In-Time loaders. The diameter of the ring (A) should be larger than the hopper opening. Choose 5/8" diameter (C) Torpedo Magnets for applications where the sight glass is 2¼" in diameter or less. For sight glasses larger than 2¼", select 1" diameter Torpedo Magnets.
