Next Generation Magnetic
Separators For Foodstuffs And
Powders
At PPMA 2018 (Stand F62) Goudsmit Magnetics of Waalre (NL) introduces a new generation of
magnetic separators. These are used to remove metal particles (>30 μm) from foodstuffs like
coffee, cocoa, malt, rice, sugar and flour, but also from other powder and bulk materials.

In contrast to previous designs, in which poorly flowing powders. showed that magnetic holding power
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
and tests in the company's own test
centre, have shown 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

CLEANING
The pneumatic magnetic bars simplify
the cleaning process. The bars are slid
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 enormous magnetic holding
power of 12,000 Gauss at the rods, the
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, the company can fit
deflectors in the magnet, providing good
control over the direction of product flows
containing weak magnetic (stainless
steel) particles. This ensures that the
product always contacts the bars.
