PLATE MAGNETS

Plate Magnets

Bunting Magnetics’ range of plate magnets are versatile and have plenty of scope when it comes to the applications and industries they can be used in, such as plastics, food, bulk handling and pharmaceutical.

They are used to capture and separate small and large metal contaminants - from fine pieces of ferrous metal through to larger chunks of tramp ferrous metal. The plate magnets are equally suited to removing metals from a range of free flowing materials, including moist, lumpy, abrasive and powdery products as well as larger materials that might cause rapid wear in tube based or magnetic cartridge separators or cause them to choke or bridge.

Thanks to their versatility, these particular magnetic separators can be selected either with very strong, permanent rare earth magnets or with permanent ceramic magnets. In addition, they can be used in both spouting and processing equipment above and below the various product flows. Larger plate magnets, which can be suspended above conveyor belts without any issues, will be needed if the application in question is dealing with bulk solids that are on the heavier side. For those that are seeking to make manual cleaning easier, these magnets have the option of being ordered with hinges attached. With this option, the magnets can be swung away from the product flow to allow cleaning to commence.

Constructed from rugged stainless steel, Bunting’s range of plate magnets can be ordered in sanitary designs. Depending on the application being used, there is also the option of three different magnet face designs, which are:

• Pole Pace – Featuring two exposed pole plates that are designed to attract and hold onto any metal contamination found in low flow applications.
• Tapered Step Face – Will work in high density applications with a fast product flow as the ferrous contaminants are held against the solid tapered step. This design means that any tramp iron and fine ferrous particles won’t wash off.
• Flat Face – Ideally suited to inverted installations, sanitary applications and low density product flows.

Plate Magnets Housing

For use inside enclosed flow lines, Bunting’s standard range of plate magnets are housed inside a stainless steel construction, known as the ‘housing’. Ideally suited to materials that might be damp or moist, that if used in other magnetic cartridge or tube based metal separators, would likely clog, block or bridge.

The housings come with optional adaptors which are intended to make any installation process easier. The housings themselves can be easily mounted to spouting that is enclosed or onto processing equipment directly. Within the housing are two strong Bunting plate magnets featuring a baffle at the top which will help to break up the product flow as well as guide it over the plates, with the aim of achieving the maximum level of ferrous contamination separation. In order to keep the cleaning process simple, the plate magnets are hinged to the housing doors as standard. The plate magnets can be swung out on the hinges and allow manual cleaning to take place without any fuss.

If a self-cleaning model is preferred, these are available in either pneumatic or manual configurations. The pneumatic option can be controlled via a remote and because of this can be installed in areas where manual cleaning would otherwise prove difficult with no easy access available. Meanwhile, the manual self-cleaning model features an interior drawer and it’s this drawer that takes any captured ferrous metals beyond the plate magnets for safe disposal. Whichever self-clean option is chosen, downtime will be reduced and any cleaning costs can be minimised.

Depending on the application, the kind of plate magnet required will vary. Product type, density, burden height, product flow and other considerations will all be things to take into account when choosing the right kind of plate magnet.
