Magnets South Africa

Double Plate Magnet

BJ Magnets’ Double Plate Magnets are made of Permanent Rare Earth (Neodymium), Samarium, or Ceramic; and are designed for effective removal of ferrous contaminants, in the aim of controlling metal fragments in products.

BJ Magnets’ Double Plate Magnets are manufactured  with heavy duty latches, hinges, and a handle for easy installation and maintenance. They are made of food grade 100% stainless steel enclosed housing; of which the magnetized plates inside are such to trap unwanted ferrous metal during the stream flow.

BJ Magnets’ Double Plate Magnets can be easily installed with limited maintenance, except the regular cleaning of captured ferrous metal; and are, not only versatile, but also cost-effective. Ideal for removing occasional tramp ferrous metal from conveyed or gravity-fed products flows.

BJ Magnets’ Double Plate Magnets are also designed for use in chutes and suspension after conveyed product. Installed on the bottom side of a chute, our Double Plate Magnets provide maximum protection as product travels through the powerful magnetic circuit. The magnetic field projects from the face of the Plate Magnets, hence reaching into the product flow-stream and ultimately pulling the ferrous contaminants to the magnet face.

We are ISO 9001: 2015

Certified by SABS

Bullet Magnet


Double Plate Magnets consist of a hinged plate attached to a housing. This allows for simple installation by removing a section of the spouting and replacing with the angled Spout Magnet. This is especially helpful when installing this type of separator in flat or a round spout.


Double Plate Magnets or Spout Magnet can be provided with a round inlet and outlet openings of which transition to the rectangular flows through areas where the plate magnet is attached. The Plate magnet is hinged, latched, and gasketed for easy access and cleaning. The  Chute Magnet or Spout Magnet is engineered to remove fine to large ferrous contaminants from high volume gravity fed product streams.


Ideal for free flowing powders and granules. Very useful for food ingredients and plastics industries.  

Manufactured to food industry required grade standard, which is 316 stainless steel; with high effectiveness and consistent performance.

Bespoke manufactured to your specific dimensions, hence in correspondence to your expected solution needs.

The Magnet strength standard is up to 10,000 gauss with  easy-clean cone.


High intensity Rare Earth magnets, which comes in nickel coated. Also available in  ceramic either, if necessary nevethless.

Manufactured to fit various pipelines ranging from 50mm – 350mm diameter, our Double Plate Magnet comes with flanges to suit square and round pipelines, for installation.

Comes with industrial or heavy-duty latches for quick release of the door.

Applications are not limited only to: Flour, Spices, Grains, Maize, Salt, Animal feeds, Pellets (Feed or plastic), Sugar or Coffee.

BJ Magnets

Double Plate Magnets are manufactured in an encased food grade stainless steel with options of 4000, or 6000 to 7000 gauss on the contact surface or higher strenght of 8000 to 10000 gauss on the contact surface; hence dependeing on the type of product or the performance expectancy  requirement. Installed in the base of an inclined gravity feed chute for an efficient extraction of ferrous metals from powder or granular materials; a Double Plate Magnet is  usually fitted before a chute-feeder.

To prevent captured ferrous contaminants from being washed off from incoming product, a trap face design should be chosen. A trap face is a tapered step on the magnets working surface. This trap is placed at a position such that magnetic fields that cause captured ferrous contaminants are drawn to the underside of the trap where they are safely held on to, preventing wash off from oncoming product. It is also important to note that the magnetic area of a Plate Magnet should cover the entire width of the spout it is protecting.

Designed to the client’s requirements, the unit is manufactured to fit the existing lines and can be supplied with relevant mountings for an easy installation. It is however important to know the suspension height of the magnet face relatively to the bottom of the material burden. This information helps in the proper selection of magnet strength. Double Plate Magnets can be made in various strengths to optimize performance in various depth of product streams. The shallower the product stream, the better the separation results will be. Heavy duty factory fabricated hinges, handle, and locking latches are provided for simple installation and maintenance. With an easy access for the regular cleaning; the magnet is manufactured in respect of the principles of the HACCP standards.

BJ Magnets is ISO 9001:2015 certified company by SABS for Quality Management System. All our Magnetic Separator Equipment are designed, manufactured and supplied under observation of the principles of the HACCP International Food Safety Standard 0909MAGSEP 1-2010. Moreso, to the bargain of their effectiveness, the internal and external aspect of the magnetic equipment is produced according to the food health and safety standard in terms of the building materials; which is austenitic stainless steel of grade 304 or 316. Thereof upon completion, a certificate of Factory Acceptance Test (FAT) which is valid for 12 months is issued; in which case the equipment shall not be subjected to the anual validation.
