GOUDSMIT DEVELOPS 10,000 GAUSS ROTARY MAGNET SEPARATOR

The recently developed 10,000 gauss rotating cleanflow magnet filters magnetic and paramagnetic particles out of poorly flowing, greasy powders in the food, pharma and chemical industries.  The magnet rotor is composed of 7 strong magnet bars, equipped with Neodymium-iron-boron magnets, each with a diameter of 32 mm. This is 40% thicker than regular magnetic bars and also used by the magnet manufacturer -the only one in the market- in the static version of the cleanflow.

The magnetic separator was developed in response to many customer requests. It is suitable for free-fall lines and captures both iron and AISI 304 and AISI 316 particles as small as 30 µm from cocoa or milk powder, for example.  An additional advantage is the higher capacity powder that the new cleanflow magnet type can process compared to the 8- or 12-rod magnet separator.  The magnetic extractor is designed to be interchangeable one-to-one with existing rotary cleanflow systems.

Capacities
The powerful magnetic bars in the cleanflow separator filter metal particles and paramagnetic particles from fatty powders and granular products. The separator is available in 3 sizes of which the largest model is suitable for product flows of up to 45m3/hour. The magnetic flux density of 10,000 gauss was measured on the contact surface of the bars. The maximum working and product temperature is 140°C, the minimum and maximum ambient temperature: -20°C to 40°C. 

The disadvantage of greasy (milk) powder is that this product does not flow well; the reason why the magnetic bars rotate in the product flow. This counteracts bridge formation and material accumulation and ensures optimal magnetic contact to capture metal contamination. The result is a high degree of separation and a clean product.
