6 Inline Magnets Clean Plastic Pellets

A UK plastics producer has installed six (6) Inline Magnetic Separators to remove ferrous metal particles from plastic pellets.

Inline Magnetic Separators are hugely versatile, effectively removing ferrous metal separation whilst being easy to install and maintain.  Mounted inside the hollow tube-like body is a strong Plate Magnet, which attracts and securely holds tramp ferrous metal.  This configuration ensures that there is no restriction to the flow of material without compromising the level of metal contamination separation.

Cleansing Plastic Pellets of Ferrous Metal Contamination

In this installation, the plastics product manufacturer needed to protect six (6) injection moulding machines from potential damage from tramp ferrous metal contamination.  When operating, the magnetic separators remove magnetically susceptible materials from a 3mm plastic pellet feed.  Commonly, FF Drawer Filter Magnets are used in such installations, but installation restraints restricted the installation of any directly above the injection moulding machines.

Due to the complexity of the installation, a Bunting engineer undertook an onsite review.  This identified the optimum location for the separation of the ferrous metal and also the best design of magnetic separator.  Subsequently, an Inline Magnet was selected for installation into an earlier location in the process where there were six (6) vertical feed pipes.  This location provided good access for metal separation, installation and regular cleaning.

For maximum ferrous metal separation, each Inline Magnet featured a high-strength Neodymium Rare Earth Plate Magnet.  This projects an ultra-strong magnetic field into the flow of plastic pellets, attracting and holding rogue ferrous metal contamination.  Periodically, on a frequency defined by the level of metal contamination, the Plate Magnet is hinged out of the product feed and cleaned.

The versatile Inline Magnet is used in a wide range of industries where material is transported in pipelines, both gravity-fed and pneumatic.
