摘要

Rotating magnets prevent the accumulation of fatty powders on the magnetic bars and guarantee a high level of separation. The new magnet system is hygienically designed in accordance with the EHEDG guidelines and can be cleaned semi-automatically. The single-piece, hydroformed housing is made entirely of grade 316 st.st. 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 s 0.6 urn). 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 air lock. A continuous, clean stream of air (+0.2 bar) feeds that air lock and blows from the inside towards the product chute. The use of rotating pneumatic magnet bars ensures that the powerful magnetic value (11,500 gauss) is in direct contact with the product. Tests have shown that in addition to separating Fe (99%) a high percentage of the AISI 304 and 316L particles are also separated.
