Make sure every person who comes in contact with the device, wears adequate personal protection (overalls, safety glasses, hearing protectors, helmet, steel-toed safety shoes etc.).

  • Page 10: Danger Of Magnetic Field

    Safety Danger of magnetic field The magnets generate a powerful magnetic field that strongly attracts ferromagnetic (Fe) materials. Always take into account that these materials may suddenly be drawn towards the magnet, very powerfully. This applies to steel workbenches and steel tools, but also to Ferromagnetic materials carried on your person, such as coins in your wallet or your keys.

  • Page 11: Moving Parts

    Safety Moving parts The conveyor belt and rollers are safeguarded. When however the protections are removed for cleaning, inspection, or maintenance, there is danger of getting jammed between these moving (rotating) parts. Danger getting jammed between moving parts!  Parts pointing out The NF separator has an open and moving system, like the conveyor belt and the vibratory feeder.

  • Page 12: Danger Of High Voltage

    Safety Danger of high voltage When installing and electrically connecting the device, make sure the activities are performed by qualified personnel. Switch off the electrical power supply before performing activities to the device! Danger – Risk of an electric shock! Always use the main power switch (on the control box) to switch off the installation in the event of a dangerous situation.

  • Page 13: Device Description

    Fe parts The NF separator is NOT suited for separating ferromagnetic particles. GOUDSMIT Magnetic Systems B.V. recommends separation of tin and ferromagnetic materials, before feeding it through the NF separator. This improves the results of non-ferro separation. Also, feeding a material flow containing Fe particles over the NF separator, increases wear, especially on the conveyor belt.

  • Page 14: Deliverable Specials

    Device description Deliverable specials Vibratory feeder Most NF separators are delivered with a vibratory feeder, it spreads the product equally over the conveyor belt and it will improve the separation. Drum Magnet A drum magnet may be included to separate ferromagnetic materials from the product flow. If included, regularly check for wear on the drum exterior and the separation flap.

  • Page 15: Drum Magnet - Principle Of Operation

    Device description Drum Magnet – Principle of Operation Product inlet Carrier Magnet Rubber segment slat Product transport around drum Separation splitter Product outlet Fe outlet The drum consists of a stationary magnet segment and a stainless steel non-magnetic shell. • The drum shell is driven by a motor and resolves in the product.

  • Page 16: Drum Magnet (Re-)Adjusting The Magnet Segment

    Device description Drum Magnet (Re-)Adjusting the magnet segment Clamp bush bolts Magnet segment 36 mm Separation segment Splitter for wrench We have already mounted the magnet segment in the correct position. It will therefore probably not be necessary to re-adjust it. If however you have a bad separation because all Fe parts fall down before they are above the Fe outlet, then you will have to rotate the magnet segment to the correct position.

  • Page 17: Eddy Current Principle

    Device description Eddy current principle The separation process of the NF separator is based on the so called “Eddy current principle”. If conductive materials are subjected to a very fast alternating magnetic field, a current will be generated. These currents are called Eddy currents. These currents generate a magnetic field, opposite to the alternating magnetic field of the magnet roller (the source magnet).
