TM Hopper magnet

TM Hopper magnet

The magnetic separator for hoppers of injection molding machines is designed to separate ferrous contaminants from free-flowing bulk materials (e.g. regrind plastics, plastic crumbs etc.). This magnet grid is used above all in conical hoppers in order to prevent penetration of unwanted ferromagnetic particles into the screw conveyors and nozzles of the injection molding machines.

Operation mode

The hopper magnet is equipped with very strong neodymium cores and that is why it catches also very small ferromagnetic particles. The already caught particles migrate to the lower part of the protective stainless steel tubes (and that is why these particles are not washed off by the continuously flowing material).

Cleaning mode

Like most of grid separators with an easy cleaning system, the hopper magnets are cleaned by sliding the magnet cores out of the protective tubes. Iron contaminants held on the tubes' surface by the magnetic field will fall off spontaneously. The easy cleaning system (unlike the fixed magnetic grates whose cores cannot be taken out during the cleaning) has a number of advantages: the cleaning is fast and easy, the caught contaminants don't need to be laboriously removed from the grid surface, the life of the protective tubes is extended and the risk of injury with a metal particle in the course of cleaning has been also eliminated.

Advantages

Besides the easy cleaning, the main advantages are the simple application, affordable prices and fast availability (these products are usually in stock).
