The rotating goudsmit magnetic separator removes metal particles of 30 µm from powders and granules, suitable for continuous processes installed in free-fall pipelines. The cleaning process does not stop the product flow—a clear requirement from a customer who wanted to recover shredded milk powder cans in a continuous process.

During the cleaning cycle, the magnets remain in the product flow. This ensures that no iron falls back into the product during cleaning, which is a problem commonly encountered with other systems. The unit can be used in industries such as chemicals, ceramics, plastics, and recycling. In the latter case, it is used to remove metal from plastic or rubber granules.

goudsmit operation

The magnetic rods in the Cleanflow magnetic separator filter out metal particles and paramagnetic particles of 30 µm from powdered and granular products. This separator is suitable for high-volume product flows (up to approximately 60 cubic meters per hour) and distinguishes itself through an extremely high magnetic flux density exceeding 9000 Gauss at the contact surface of the rods.

A disadvantage of fat (milk) powder is that the product does not flow well. This is why the magnetic rods rotate within the product flow. This ensures the bars remain clean and allows optimal contact between metallic contaminants and the magnets. The result is not only high separation efficiency but also high metal separation capacity.

goudsmit cleaning

For many magnetic separators, it is necessary to remove the magnets from their housing during the cleaning cycle to clear captured metal particles. However, Goudsmit (Goudsmit) knows from experience that this method carries the risk of metal falling into the product flow and requires production to be paused to clean the separator.

This is why we designed the new system so that the magnets remain in the product flow during cleaning. Only the sleeves contaminated with metal around the magnetic rods are removed along with the metal particles and replaced with clean sleeves. This allows the magnets to be cleaned without stopping production.

How does goudsmit electromagnetic filtration work?

A magnetic rotor with strong neodymium magnetic rods is located in the center of the product flow. Products contaminated with ferrous particles always pass through multiple magnetic rods as they flow through the separator.

The magnets attract passing ferromagnetic impurities. The captured particles adhere to the magnets, while the purified product continues to flow.

How does goudsmit cleaning/iron removal work?

Production can continue during cleaning because the magnetic rods of these Cleanflow units are fixed horizontally in the product channel. This means magnetic contaminants never pass through.

The pneumatic tubes surrounding the magnetic rods are always located in the product channel and sequentially positioned over the left and right iron discharge chutes.

After giving the start signal for the iron removal cycle, the tubes slide along the magnets under air pressure to the left or right iron discharge tray. Rings on the tubes pull the captured iron particles out of the product channel. Once detached from the product channel, the iron particles fall off the tubes without being influenced by the magnets.

The time interval between two iron removal cycles can be set locally, on the machine's PLC controller, or on a central controller.
