Overhead Magnetic Separators & Conveyor Magnets


Ensure product purity, protect equipment and prevent downtime

Shields magnetic separators and belt magnets serve as an insurance policy in industrial applications ranging from food and aggregate processing to coal mining and plastics production and recycling. Our separation equipment removes damaging ferrous metal from raw and finished materials throughout all stages of production including conveyor belts, grain hoppers and flow systems.

Adding overhead separators, drum magnets or crossbelt magnets can save your organization thousands of dollars in lost product and materials, damage to your production equipment and help improve up-time. All of our magnetic separators use powerful Grade 8 permanent magnets and can be ordered to spec, including electromagnets. We’ll work with your to customize a separation system that will fit your facility and application perfectly.

All of our industrial magnets carry a lifetime guarantee on strength

Utilizing state-of-the-art technology and the most advanced materials available, Shields magnetic sweepers are innovative, functional, and effective.  Our entire line of sweepers carries a lifetime guarantee on strength and a full product performance guarantee. All of our industrial magnets originate in the USA.

Companies Rely on Shields Separator Magnets

Conveyor Magnet for High Volume Industrial Flow

Type CM3 Super Strength Conveyor Magnet

Our Type CM-3 is designed to remove larger ferrous metal such as bucket teeth, drill bits, and rebar from high-volume industrial flow. Capable of living items up to four inches below the unit, the Type CM-3 Super Strength Conveyor Magnet is a “no-maintenance” item and carries a lifetime guarantee on magnetic strength.

Conveyor Magnet for Light to Medium Volume Industrial Flow

Type CM-1 Conveyor Magnet with Auto Release

The Type CM-1 Conveyor Magnet is a versatile, portable and extremely effective way to remove random ferrous metal during product processing. Idea as back-up “Insurance Policy” when used in conjunction with a larger crossbelt magnet to retrieve small “fines” which get past the crossbelt, or as a stand-alone for light to medium volume industrial flow.

Permanent Magnetic Separator for Processing Environments

Stationary Separator Magnets

Permanent Suspension Magnets are designed specifically for the extraction of occasional tramp iron from material being processed on the conveyor belt, vibratory feeder or gravity chute. These overhead magnets are constructed using Grade 8 high power ceramic magnets and require no electricity, unlike electro type units.

Overhead Magnetic Separator for Conveyor Belts

Cross-Belt Magnets

Crossbelt or belt magnets, also known as overhead magnetic separators, offer a practical and efficient method for separating ferrous metal from fast-moving materials on conveyors. Our belt magnets utilize Tri-Polar Magnetic Circuitry, exclusive to the industry.

Pulley Magnets Protect Against Tramp Iron Contamination

Magnetic Head Pulleys

Our head pulleys and drum magnets provide continuous protection against tramp iron contamination of both large and fine metal particles. We offer magnet sizes for every application, as small as 4″ diameter. Our magnetic pulleys are available in regular strength and a “high power” version for more extreme applications.

Frequently Asked Questions

Q: How much are the belt magnets?

A: We have over 40 sizes of belt magnets and stationary separators so first we have to determine what your application is. This is a very fast process and we can do it over the phone or you can fill out the on-line criteria sheet.

Q: Are the units in stock?

A: We stock many sizes but if not, turnaround is quite fast.

Q: Do the magnets come with mounting hardware?

A: The stationary separators come equipped with sling chain for suspension, 4 turnbuckles for attaching and a swipe arm for easy cleaning.  The Self-Cleaning Crossbelt Magnets are equipped with turnbuckles for mounting.

Q: Are these electro-magnets? 

A: We do offer electro-magnets however unless your application is extreme, you do not need an electro, given today’s technology a permanent magnet will do the job perfectly. We offer Tri-Polar Magnetic Circuitry in most units, which is exclusive to the industry. This eliminates peripheral “leakage” and directs magnetic field directly down to the conveyor.

Q: What sort of power is required?

A: 3 Phase 230 or 460 is standard to drive the belt on the Crossbelt Magnets. You may also choose hydraulic drive at no extra cost. The Stationary Separators require no power source.

Q: Are these self-cleaning units?

A: We offer both self-cleaning and manually cleaned units. The self-cleaning units are called “Crossbelt Magnets” and have continuously running belts rotating around the magnet. The manually cleaned units are called “Stationary Separators” and these units are equipped with either slide trays for easy debris removal or swipe arms.

Q: Do these come with chains?

A: All the units are equipped with suspension eyebolts and sling chain.

Q: Do you offer anything smaller?

A: We have a “one-size fits all” unit, the Type CM-3 Conveyor Magnet, which is essentially a low cost insurance policy for lighter applications or to be used in conjunction with a larger unit or a magnetic head pulley. These can be purchased directly on the site or by calling us as well.

Q: What is the Warranty?

A: All units carry a lifetime guarantee on magnetic strength. There is a one year warranty on belts and parts.

Q: How do These Ship?

A: Some of the smaller Type CM-3 Conveyor Magnets can ship UPS or FedEx Ground. The larger units ship common carrier.
