Star-shaped hopper magnets SM

General principle of the function of Star-shaped hopper magnet SM

A magnetic grate of a star design for the hoppers of injection moulding machines is intended for the separation of iron tramp from free-flowing dry materials (such as regranulates, crushed plastic materials, plastic crumb, rejected mouldings etc.). The magnetic grid protects the moulding machines (with standard cone hoppers) and other processing equipment from damage by ferromagnetic particles.

While the bulk powder material falls through the grid magnet, a very strong magnetic field (generated by neodymium NdFeB magnets of the hopper magnet) traps all metallic particles on the surface of the neo magnets. Thanks to the magnets made from rare earth ores the magnetic impurities captured on the tubes are not carried away by the stream of the continually poured material (what happens in case of separators fitted with weaker black ferrite magnets).

How is star-shaped hopper magnet cleaned?

During the cleaning procedure the grate magnet is taken out of the hopper and the captured ferromagnetic particles are removed either mechanically or by a stream of compressed air. The star-shaped hopper magnet is very effective, but also easy to install and transport (from one application place to another), practically maintenance-free and inexpensive to acquire and operate. The design as well as the size of the star-shaped magnetic grid for plastic extrudes & injection moulding machines can be adjusted to client's requirements.
