Stationary
This maintenance-free design has no moving parts and requires
no power supply. A convenient three-point sling assembly is
included with your magnet. Just suspend it over the conveyor
or over the headpulley and it’s ready to pick up those stray
metal fragments before they can cause damage to downstream
equipment. When the magnet surface starts to fill up, swing
the magnet away from the conveyor and dislodge the
attracted metal. Swing it back over the conveyor and you’re back
in operation.

Installation
Dings permanent overhead magnets are built in 2 types: In-line and Crossbelt. An In-line type is
installed over a conveyor head pulley so that the magnet face is parallel to the travel direction of
material falling off the conveyor. The head pulley must be made from non-magnetic material. This
location is preferred because separation efficiency is better
when the magnet is located over where the conveyed IMPORTANT:
material opens up during its path through the air. IN-LINE installation is preferred because
A Crossbelt type is installed over a conveyor so that the separation efficiency is better when the
magnet is at a right angle to the travel direction of the magnet is located over where the conveyed
material on the conveyor. If the magnet cannot be installed material opens up during its path through the air.
over the head pulley, install it over a flat section of the
conveyor. Magnetic performance may be affected by
magnetic material in the field; see “Non-magnetic area” on the next page.
Suspension height is critical to the performance of the magnet. This distance is measured from the
bottom of the magnet face to the surface of the material handling belt. Elevate the magnet to the
suspension height that is appropriate for the application. An appropriate height is 2” – 3” above the top
of the conveyed material or the height specified at the time of purchase. If a height is specified,
measure it as the middle of the conveyor belt, on its surface, up to the magnet face – the bottom surface
of the magnet.
If the magnet is too high above the burden, sufficient magnetism may not reach into the burden and
cause a loss in separation efficiency. For best results, crossbelt separators should be centered over the
belt and parallel to the slope of the belt conveyor.

Non-magnetic area
Magnetic performance is affected by magnetic material in the field; in the shaded area, no
construction parts that can be magnetized are permitted. Pulleys, rollers, frames, supports,
etc., must be made of material that cannot be magnetized.
When installing the magnet in-line, the head pulley must be non-magnetic.

Patented Flux Design — Lifetime Guarantee on Magnetism !
The Dings patented flux control circuit (DFC) was a breakthrough in the design of
permanent magnetic separators. It eliminates internal leakage between magnetic
poles and improves separating performance.
Conventional magnetic circuits contain air or filler material between the magnetic
poles. This gap causes the flux, or excess magnetism, to be wasted. In Dings DFC design, blocking magnets
are strategically positioned in the spaces between magnetic poles. These blocks redirect the flux outward,
into your product, converting wasted force lines to working force.
The overall strength of the magnet is improved three ways – the field is stronger, the field is extended deep-
er and the field pattern is more uniform and therefore more efficient. By efficiently using the magnetism, a
Dings magnet can be sized to provide the right amount of magnetic power for your application – a potential
savings in weight and cost.
In-House Testing
Unsure which product is best for your application?
Just send us a sample of your product with a brief description of what you are trying to accomplish. We’ll be
happy to test it on actual equipment at our in-house testing laboratory at no charge. We will then give you
a report and recommend the best equipment for your particular application.
Custom Design
Don’t see exactly what you’re looking for in our standard products? Our team of highly experienced sales
engineers will work with you to design the perfect separator for your application. Using state of the art
computer modeling and design, our engineers will provide you with certified prints prior to production to
ensure that everything meets your requirements.
Rebuilds
If your magnet has been damaged and funds aren’t available for replacement, consider having Dings rebuild
it. In many cases, we can bring a magnet back to near-new condition at a cost substantially less than that of
a new one.
