METAL SEPARATION SYSTEMS Metal is one of the materials most commonly used in industry. Nevertheless ... iron particles are undesirable in finished products, semi-finished products, or raw materials – particularly in the food industry. Companies make every effort to remove as much of this contamination as possible. It will be self-evident that iron is removed with magnets. During the past decades Bakker Magnetics has become specialized in the development and manufacture of systems for industrial iron-separation processes. Bakker Magnetics’ efforts have resulted in the acquisition of a great...

Bakker Magnetics’ metal separation systems are of a modular design, as a result of which they can readily and rapidly be installed in both new and existing raw-material transport systems. Bakker Magnetics’ applications staff will be pleased to advise you in drawing up the optimum solution for your specific ironseparation problem. To this end you can make use of the questionnaire enclosed in an appendix to this brochure. We will then reply as quickly as possible with tailor-made advice. A distinction can be made between a number of basic iron-separation principles, each of which offers...

P l a t e m a g n e t F D A / V I Plate magnets are used to remove iron from product flows on conveyor belts, vibratory feeders, during free fall, in vertical or inclined pipes, under slide plates, etc. This type of plate magnet includes a Neodymium magnet system of an optimum power, and designed such that the unit offers an extra strong and deep-reach magnetic field. The magnet system is brought in as close as possible contact with the raw material. The system can achieve an extremely high efficiency, depending on the product, the particle size and the conveying velocity. The standard...

Grid magnet RV/VI Permanent grid magnets fitted in hoppers or pipes can be used for the removal of iron particles from raw-material flows. These grid magnets are comprised of powerful magnetic bars which guarantee the thorough removal of iron particles from products passing through the grid in free fall. The iron particles are captured by the filter bars. The grid magnets are cleaned by removing them from the product flow and then manually removing the iron particles. Grid magnets are usually employed in free-flowing products contaminated with small amounts of iron. In many situations a...

M A G B O X [ 8 ] B A K K E R M A G N E T I C S The MAGBOX is a complete iron-separation unit for installation in pipes. This unit can readily and rapidly be installed in existing pipes. The standard types of MAGBOX housing are supplied without grid magnets. The housing can be equipped with one or two grid magnets, as required, whereby use can be made of the standard RV/VI grid magnets of the easy-clean RVEC/VI grid magnets (please refer to page 7). The product falls freely through the system; iron particles in the product are captured by the grid magnets. The front of the MAGBOX is...

A semi-automatic version which is also available is even easier to clean. The cleaning procedure is as follows. The product flow is interrupted. The quick-action clamps are released, and the magnet system together with the stainless-steel jackets are slid out of the housing. Once the entire magnet unit has been slid from the housing the magnetic part is slid out of the extractor; the iron particles which are then released from the sleeves will fall down outside the housing. The iron particles can then be collected separately. All the standard MAGBOX systems are fitted with pre-drilled...

P O W E R - M A G [ 1 0 ] B A K K E R M A G N E T I C S This revolutionary model has been especially designed for applications which require a combination of a low overall height, a powerful magnet system in the product flow, and a minimal risk of bridge-building. The increased distance between the magnetic units as compared to conventional grid magnets renders this system suitable for use with products which do not flow freely and/or readily adhere to or accumulate on surfaces. This system is also ideally suited to the separation of iron particles from coarser products or hygroscopic raw...

The Power-Mag can also be supplied in a remote-controlled self-cleaning version. The product flow needs to be interrupted before activating the cleaning cycle. After the activation of the cleaning cycle by an electrically-operated valve two pneumatic cylinders slide the magnet system and stainless-steel sleeves from the housing. Once the entire magnet unit has been slid from the housing two further pneumatic cylinders slide the magnetic units clear from the sleeves; the iron particles are then released, and collected via an iron-particle outlet. The magnet system is then returned to its...

The chute magnet system has been developed for the efficient removal of iron particles from raw materials which do not flow freely, such as powders, and tacky or oily products, and/or scrap. The system is installed in one of the pipes used to transport the raw materials during the production process. The unit is located in a fully-welded stainless-steel housing which can be installed in the pipe in a manner such that it in effect constitutes an integral part of the pipe. To this end use can be made of the adapter pieces illustrated on page 16. Chute magnets are characterized by the location...

The BKM-AUT/VI chute magnet is equipped with remote controls and a fully-automatic cleaning system. A valve box incorporated in the system ensures that the iron particles captured by the magnets are discharged outside the housing during the cleaning process. This system is suitable for non-continuous processes. After stopping the material flow the cleaning cycle can be activated by giving a signal to an electric value. The valve box rotates and the magnets are moved outwards to remove the magnetic field from the housing. The captured iron particles are released and discharged via the valve...

Magnet systems of the BKM-HD/VI type have been developed especially for use in pneumatic-transport systems operated at an overpressure. The standard unit is available in two dimensions, i.e. a housing 150 mm square and a housing 200 mm square. The system is supplied with a separate receiving tray which must be slid into the opening at the base of the housing when cleaning the unit. This opening is hermetically sealed during the production process. Execution: simple manual cleaning permanent magnet Material: stainless steel grade 1.4404 Magnetic section: 2 plate magnets, type FDA/ND The...
