Magnetic Separators for Powders

The Goudsmit Magnetics Group introduces a new generation of magnetic separators that removes metal particles (<30 µm) from powders in the food, chemical, ceramic, and other industries.

The Easy Clean flow magnet features user-friendly cleaning, improved flow, and high Gauss values of the bars. In contrast to previous designs, in which such magnets were fitted with two layers of thin (Ø25 mm) bars, the new design contains a single row of Ø50 mm thick bars. New measurement techniques, including simulations of magnetic fields, show that this results in a higher separation yield. This is because the thicker bars remain in contact with the magnetic particles longer. An additional benefit is the reduced height of the magnet as a whole, which means it requires less installation height. Furthermore, a single row of bars results in improved product flow, which is particularly beneficial when it comes to poorly flowing powders.
The pneumatic magnetic bars simplify the cleaning process. They slide out along a guide and, once outside the housing, the magnets are exposed by blowing them out of the bars. A plate then retains the captured metal particles, after which they fall into a collection tray.

With its large magnetic holding power of 13,000 Gauss at the rods, the Easy Clean flow magnet is suited for the separation of small (>2 mm) stainless steel particles. Tests and measurements showed that magnetic holding power alone is not enough to separate stainless steel particles. It is also of critical importance that these particles come into contact with the bars as they flow past. To accomplish this, deflectors can be fitted into the magnet, providing control over the direction of product flows containing weak magnetic (stainless steel) particles. This ensures that the product always contacts the bars.
