Waalre-based Goudsmit Magnetics has developed a new pipe magnet that requires half the
installation height of its predecessor and is also twice as strong. Manufactured entirely from stainless
steel, the magnetic separator contains a core of neodymium (NdFeB) magnets and creates a flux
density of 12,000 gauss. The conical-shaped magnet core contains more pole plates, so even 30 μm
particles stick to more engagement points. This results in a higher degree of separation and also
makes it possible to capture smaller metal particles in addition to coarse ones. Steel particles present
in the product flow such as bolts, nuts, washers, screws, small metal balls, broken threads and clips
can be effortlessly separated from grains, corn, flour, wheat flour and other incoming goods flows.
The new magnet system is suitable not only for mounting in free-fall pipes, but also for pressure
pipes. The stainless steel bullet magnet can be used in food but also other industries.
Low installation height & compact design
The 12,000 gauss pipe magnet was developed in response to specific market demands. The first
requirement was to develop a pipe magnet with a low installation height that, with a small
adjustment in terms of pipe length, can be easily integrated into existing processes. This, together
with the high flux density, means that the magnet can already be used at goods intake. An additional
advantage is that the pipe magnet captures smaller metal particles in addition to large metal
particles, improving product quality. This prevents dust explosions and damage to machinery,
resulting in production stoppages. The stainless steel pipe magnet can optionally be fitted with
various flanges, such as DIN, Jacob etc. This makes the product widely applicable.
Quick access for easy cleaning
Despite the strong permanent magnetic core, the magnet is easy to clean. Through the door with
vertical suspension, inspecting for contamination levels is seconds work. The magnet can be opened
and cleaned by hand or a scraper. Smaller metal parts, such as balls or broken threads, can be easily
pushed above the tapered top of the magnetic core and then removed. This is an improvement over
previously designed versions. To prevent the magnet from being opened during the production
process, it is possible to fit the stainless steel pipe magnet with a safety switch.
