Permanent grid magnet

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 number of grid magnets are installed above each other; to this end two different versions are available in which the magnetic bars are positioned out of line with each other. This “staggered configuration” improves the contact between the product and the magnetic bars. The sophisticated magnet configuration guarantees an extremely powerful and intense magnetic field. The design is based on an optimum combination of a field which is as powerful as possible at the surface with a working depth which is as deep as possible.

Grid magnet Easy Clean
Grid magnets can also be supplied in a special easy-clean version. This type of grid is fitted with what is referred to as an extractor. This stainless-steel sleeve renders the grid magnets
extremely easy to clean. Sliding the magnetic part from the extractor releases iron particles which were captured by the magnet; the entire unit can then readily be cleaned or rinsed
clean. The extractor sleeves are open at both ends, thereby preventing product from being trapped in the system, and in turn precluding the risk of microbial growth.

A handy HDPE strip simplifies the replacement of the magnetic part in the extractor
