Pyörrevirtakiillotuslaitteet

Pyörrevirtakiillotuslaitteet, often referred to as eddy current separators, are specialized machinery used in material processing and recycling industries. Their primary function is to separate non-ferrous metals from other materials like plastics, glass, or aggregates. The core principle behind their operation is the induction of eddy currents within conductive materials.

A typical pyörrevirtakiillotuslaite consists of a conveyor belt system and a rapidly rotating magnetic rotor positioned at the end of the belt. As a mixed stream of materials passes over the rotor, the alternating magnetic field induces electrical currents, known as eddy currents, within any non-ferrous metallic components. These induced currents generate their own magnetic fields, which oppose the field of the rotor.

This opposition creates a repulsive force that effectively repels the non-ferrous metals, causing them to be ejected from the main material flow at a different trajectory. Ferrous metals, such as iron and steel, are attracted to the magnetic rotor and removed by a separate magnetic separator upstream. Non-metallic materials, lacking conductivity, are unaffected by the magnetic field and follow a predictable path, allowing for a clean separation.

Pyörrevirtakiillotuslaitteet are crucial for recovering valuable metals like aluminum, copper, and brass from waste streams, contributing to circular economy initiatives. They are commonly found in municipal solid waste processing, scrap metal yards, and industrial recycling facilities. Their efficiency and reliability make them an indispensable tool for modern material recovery.
