Stationary Separator Magnets

Exclusive to the industry, Magnetic Separators utilize Tri-Polar Magnetic Circuitry, eliminating most peripheral magnetic leakage and directing magnetic field straight down, improving and increasing the strength compared to equivalent sized magnets. Magnetic intensity in excess of 400-500 gauss at the recommended working gap retained permanently when used under normal operating conditions.

PSM
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 magnetics and require no electricity, unlike electro type units.

The magnetic separator, usually a rectangular pattern, is suspended over the material being conveyed, while the ferrous material is extracted and held against the face of the magnet until manually cleaned off.

For safety and ease of cleaning, swipe arms or slide trays are standard on all magnetic separator units to assist in cleaning without having to touch the tramp metals. And when comparing to electro magnets, they are less expensive to purchase, operate and are virtually moisture, corrosion and flame proof.

Typical applications for the use of Permanent Suspension Magnets include removal of iron from coal, stone, fertilizers, recycled asphalt, stag, gypsum, ores and similar materials where contamination by tramp iron is occasional and continuous separation is not essential and the primary purpose is processing machinery protection. These overhead magnets can be mounted either horizontal or inclined over the head pulley. All stationary magnets are fitted with a set of adjustable suspension chains designed to suit application and attach to suspension lugs. Preferred installation position is above the head pulley where the burden is spread out and the material is in virtual suspension as it is discharged from the conveyor.

Magnetic Separators can be mounted on a variety of structures, including runway beams (using a trolley for suspension and movement) or A-Frame structure. Size availability covers the entire range of conveyor widths and material burden depths to 25″, depending on material being separated.

WARRANTY
A Limited Lifetime Warranty on the magnet system is offered, against loss of magnetic strength, when used under normal operating conditions. Magnet systems are available in over 110 models to match any conveyor width, from 12″ to 84″ or burden depth to 25″, depending on the material being separated. With as many as 50 units always in stock at our warehouse, including many of the popular sizes, they are ready for immediate delivery.

TRI-POLAR© MAGNETIC CIRCUITRY

Tri-Polar © Magnetic Circuitry is relatively new on the magnet system scene.
It is the ultimate in Permanent Magnet technology, not available from any other magnet system manufacturer.
Shields Company/Mastermag have developed this computer designed magnetic circuitry using their rare, large and very costly 13 Ton Magnetizer*, one of only four in the world. It is available as standard on SHIELDS/MASTERMAG PSM STATIONARY MAGNET SERIES in the larger sizes.
*Magnet system manufacturers traditionally magnetize ceramic blocks before forming the circuit in a stainless steel box. Due to the nature of magnets – wanting to repel each other – there is a limitation on how many blocks can be stacked on top of each other. SHIELDS/MASTERMAG forms their circuit in the stainless steel box prior to magnetizing. After the circuit is completed and box sealed, it is immersed in the 15 Ton Magnetizer for three (3) separate sessions thoroughly magnetizing the system creating the Tri-Polar© Magnetic Circuitry.
The evolution of Permanent Magnets have taken some dramatic leaps in the past 15 plus years. First, is the quality of the material used to make a permanent magnetic system. In the case of SHIELDS/ MASTERMAG, we use only Ceramic 8, as do most reputable magnet companies. This material, also known as Strontium Ferrite, has allowed permanent magnets to last longer (SHIELDS/MASTERMAG offers a Limited Lifetime Warranty against loss of magnetic strength – see details below) and produce more field strength (gauss or force index).

In many applications, Permanent Industrial Magnets can be more or as effective as Electromagnets and have considerable advantages over Electros.
Longer warranty
Lower Profile
Lighter
No costly power required
Less costly to purchase and operate

Previous limitations of Permanent IndustrialMagnets have been:
Magnetizing all iron/steel around or underneath the magnet as a result of peripheral magnetic leakage
Not as strong as Electros

But with the Tri-Polar© Magnetic Circuitry as part of SHIELDS/MASTERMAG’s larger Permanent Industrial Magnet Series, Permanent Magnet Technology will never be the same. As a direct result of this new technology, peripheral magnetic leakage is all but eliminated, directing the magnetic field straight down and creating a stronger magnet. These Series of magnets are approximately 30% more powerful than the competing units of the same size and equivalent or superior to many sizes of Electros. As a result of this increase in strength and the potential for use in extreme applications – Manganese Wear Impact Plates are included as standard.
