Goudsmit Magnetics Group Hydrohansu-type rotating clean flow magnet

Goudsmit Magnetics Group’s Hydrohansu-type rotating clean flow magnet is suitable for the removal of very fine iron (Fe), AISI 304 and 316L particles in the dairy industry and for products such as baby food. It is also suitable for use in the sugar and lactose industries.

Rotating magnets prevent the accumulation of fatty powders on the magnetic bars and provide a high level of separation.

The single-piece, hydroformed housing is made entirely of grade 316 stainless steel and therefore has no dead ends, sharp corners or welded seams, which prevents bacterial growth.

The complete system has a high-quality surface finish (Ra ≤0.6 µm). The magnet rotor has pneumatically operated magnet bars, is mounted in the door and rotates on a bearing. To prevent product from entering the space between the rotor and the housing, it is fitted with a removable labyrinth airlock. A continuous, clean stream of air (+0.2 bar) feeds that airlock and blows from the inside towards the product chute. The use of rotating pneumatic magnet bars ensures that the powerful magnetic value (11,500 G) is in direct contact with the product.

The semiautomatic cleaning process can be performed during a production stop. After the rotor is released and pulled out manually, compressed air internally shifts the magnet packs to the cleaning position. This provides a quick, easy and safe cleaning method in which the metal particles are carried away. Sensors ensure that all these steps can only be performed in the correct order.
