Drawer Magnets for Free Flowing Material Bunting HF Series Drawer Magnets are
equipped with powerful magnetic cartridges
to handle a wide range of separation tasks in mechanical or gravity flow applications. They can be ordered with one or more cartridge trays. The more trays, the more contact with the product stream. A minimum of two staggered trays is recommended, where space will allow, so that material can flow in a zig-zag pattern from one cartridge tray to the next for exceptionally thorough cleaning. HF Series Drawers are available in utility, powder, food, and sanitary construction grades with three cleaning options and stainless steel housings. We supply custom transitions to match your spouting.

Self-Cleaning Options Save Labor and Downtime

In the standard configuration, ferrous tramp is removed from the cartridges by sliding the trays out of the housing and wiping them off by hand.

Self-Cleaning HF Drawer Magnets are designed to fully extend the magnetic cartridges outside the housing. As these tube assemblies travel outside the housing, grommets wipe the tubes clean all the way to their nonmagnetic tapered ends. This ensures that each cartridge is fully wiped and prevents captured tramp iron from reentering the housings. Self-cleaning models are available in both manual and fully automatic pneumatic versions. Pneumatic units operate at the touch of a remote switch so they can be installed in hard-to-reach locations.
■ Pre-engineered for fast field installation.
■ Transitions available for round, square, or rectangular spouting.
■ Multiple trays of staggered magnetic cartridges provide increased contact with product flow for more complete metal capture.
■ Order Ceramic, Alnico, or Rare Earth
magnets to get the holding force right for your application.
■ Specify mild or stainless steel construction.
■ Housing design allows easy access to magnets.
■ Self-cleaning models offer labor-saving
convenience.

PLATE MAGNETS FOR SPOUTING AND PROCESSING EQUIPMENT

Bunting Plate Magnets install easily in chutes to remove ferrous fines, as well as large pieces of tramp iron, from many types of free-flowing and pneumatically conveyed material. They can handle powdery, moist, lumpy, and abrasive products and large debris that might choke, bridge, or cause rapid wear in cartridge-based separators.

Plate Magnets can also be installed above conveyors or below conveyor drive pulleys to capture contaminants as material drops from open belts. Standard installation kits include
a pre-drilled hinge, latch, and other hardware to ensure easy mounting.

All Bunting Plate Magnets have 100%
stainless steel exteriors to resist the corrosive effects of mild acids, moisture, and washdown. Magnetic pole faces and tapered step faces are 410/416 SS. Everything else is 300 series stainless steel.

NeodymiumPlate Magnets are continuously welded to make a watertight seal that also protects against corrosion. Redesigned cast stainless steel hinges have smooth, easily cleaned surfaces and can be quickly disassembled  for thorough pin-and-cotter sanitizing.

Flat Face Model is recommended for low-density product flows, inverted installations, and applications that must be kept sanitaryor where possible damage to fragile product is a concern.
Pole Face Model is intended for low-flow applications. It features two exposed pole plates to capture and hold small, fine contaminants.
Tapered Step Face Model is designed to hold ferrous debris against its solid tapered step to prevent wash-off of tramp iron and fines even in highdensity applications and when product flow is rapid.

The stainless steel housings mount easily to enclosed spouting or directly on processing equipment. Optional square, rectangular, and round adapters can be supplied to your specifications for ease of installation. A baffle at the top of the housing helps break up clumps and directs product flow over the unitʼs two powerful Plate Magnets. Bunting Plate Magnets come in several faceplate styles to cover a wide range of applications. They are available either with permanent Ceramic Plate Magnets or with high-energy permanent Rare Earth Plate Magnets that can capture fine metal particles and slightly magnetic debris. Plate Housing Magnets can handle powdery, moist, clumpy, or abrasive materials that might choke or wear cartridge-based separators.

HUMP MAGNET SEPARATORS FOR

HIGH-VOLUME PRODUCT FLOW

Bunting Hump Magnet Separators come in Hump and Half-Hump housings designed for installation in enclosed flow lines or on processing equipment. We can supply adapters made to your specifications. Ceramic magnets
are standard – with optional high-energy Rare Earth magnets and stainless steel construction. Housings handle moderate positive and negative pressures. The angled shape directs the product flow into the magnetic field, helps prevent build-up and bridging, and also breaks
up clumps of product for increased protection against entrapped ferrous debris.

WEDGE MAGNETS FOR ECONOMICAL PROTECTION OF PELLET MILLS AND OTHER GRAVITY-FLOW SYSTEMS

Bunting Wedge Magnets provide economical
protection against tramp metal damage for pellet mills and other equipment used to process particulate or semi-solid materials under gravity flow. Wedge Magnets are ideal for installation in narrow, vertical, or steeply inclined chutes that are easily accessible and can be opened for inspection and manual cleaning. The wedge shape resists bridging and diverts the product flow across the front and back collection surfaces, where Ceramic magnets located behind the outer stainless steel skin capture and hold ferrous contaminants.
■ Designed for installation in narrow chutes
where materials are under gravity flow.
■ Stainless steel skin resists wear and corrosion.
■ Minimum mounting space required.
■ Wedge shape helps prevent product build-up
and bridging.

IN-LINE MAGNETS FOR GRAVITY OR PNEUMATIC SYSTEMS

Bunting Gravity and Pneumatic In-Line
Magnets feature full-flow architecture that
leaves the product stream unobstructed.
Tapered transitions guide material directly over
the face of the hinged plate magnet, which
swings away from the housing for quick
external cleaning.

CENTER-FLOW MAGNETS FOR DILUTE-PHASE PNEUMATIC SYSTEMS

Center-Flow In-Line Magnet Separators are
engineered to remove ferrous fines as well as
larger pieces of tramp iron from dry particulates
as they travel through dilute-phase
pneumatic or gravity-flow conveying lines.
To achieve optimum contact with the product
flow, a bullet-shaped magnet is suspended in
the centerline of the housing. This tapered,
exposed-pole cartridge has a stainless steel
“nose cone” to direct the flow of materials
around the magnet. The magnetʼs tapered poles allow ferrous fines to collect out of the direct air stream, and the trailing end of the magnet is an active pole so that any tramp metal that might be swept down the cartridge will collect there.

■ Installs easily in any position with factory
supplied compression couplings.
■ Placement in vertical run makes optimum
use of magnetic field.
■ Durable stainless steel nose cone directs
material around bullet-shaped magnet.
■ Tapered pole design lets metal fines collect out of the air stream.
■ Unclamp the cover and swing the magnet
out for cleaning.
■ Available with Ceramic or Rare Earth magnets.
■ Self-cleaning models save time and labor.

SUSPENDED PLATE MAGNETS FOR INSTALLATION ABOVE CONVEYORS

Bunting Suspended Plate Magnets are placed above open conveyors to snap up ferrous objects and fines found in grains, feedstuffs, raw and processed food products, dry chemicals, and other particulates. In recycling applications, they can be used to capture tramp iron from recycled material before and after it goes through a grinder or shredder. They come in sizes matched to common belt widths and are outfitted with eyebolts to aid in handling and overhead suspension. Our heavy-duty 950 Suspended Plate Magnets come standard with high-density Ceramic magnets that provide an impressive halfpound pull at 9 inches and capture ferrous contaminants at belt speeds up to 300 fpm.

CROSS-BELT SEPARATORS FOR CONTINUOUS OVER-CONVEYOR SEPARATION AND SELF-CLEANING OPERATION

Cross-Belt Separators provide continuous
removal of ferrous contaminants from material
on open conveyors. Tramp iron falls from the
unitʼs cleated belt as it moves the captured
metal debris beyond the magnetʼs face and out
of the magnetic field.

           
Bunting 950 Series Magnetic Cross-Belt
Separators are made for heavy-duty
applications like recycling municipal trash,
construction debris, tires, or heavy plastic
materials. These units provide deep 10"
reachout and will magnetically remove ferrous

DRUM MAGNETS FOR HIGH FLOW RATES AND HEAVY METAL CONTAMINATION

Magnetic Drums and Drum Separators
are self-cleaning and provide continuous removal of ferrous contaminants from a wide range of free-flowing bulk and granular materials in high-volume applications. When material flows onto
the drum, a stationary magnetic assembly inside the unitʼs shell captures tramp metal and holds it securely to the drumʼs stainless steel
surface. With contaminants removed, the good product falls freely to a discharge point. As the drum rotates, cleats sweep the ferrous debris through and out of the magnetic field. The tramp metal is discharged separately, creating continuous self-cleaning separation.
■ Designed for continuous separation and
cleaning.
■ Ideal for highflow, heavy contamination applications.
■ Stainless steel drum and mild steel or stainless steel housings.
■ Drums can be ordered with or without housing.
■ Available with Ceramic or Rare Earth magnets.
