The new self-cleaning clean-flow magnet removes very fine iron particles (as well as RVS dust) as little as 25 mhu from powders and granules. The magnet can be used in free fall systems in the chemical and pharmaceutical industry. Once the particles have been caught they are released from the magnet by simply pressing the button and are then easily disposed of. This allows the magnet to be mounted in places that are difficult to access as well. The system is currently operational in a large German chemical concern for making Makrolon, used for the production of CDs, free from iron.
Magnet
The self-cleaning clean-flow magnet consists of two rows of powerful Neoflux ® magnetic bars that have been mounted on top of each other. As a result, the product always hits the magnet. The magnetic bars consist of Neoflux® (neodymium-iron-boron) magnets. This way a magnetic value of 12,400 Gauss can be achieved. The system has a low height of 250 mm.
Cleaning
The cleaning cycle can be started after the production process has been stopped. The entire set of magnets is taken out of the product flow during the cleaning process. A pneumatic control blows away the magnets inside the tube, thus removing the magnetism. The iron parts let go and through a chute disappear into a receiving container. After cleaning, the magnets return to the tubes and production is continued.
