An Eddy Current Separator consists of a short belt conveyor with its drive located at the return end, and a high-speed magnetic rotor system installed at the discharge end. The magnetic rotor, housed within a separately rotating non-metallic drum, operates at speeds of up to 3,000 revolutions per minute, while the outer drum cover rotates at the same speed as the Eddy Current Separator’s belt conveyor.
Goto qunfeng to know more.
As the rotor spins at these high speeds, it produces a changing magnetic field. The strength of this field depends on the rotor's speed and the number of magnetic poles.
When a conductive metal piece passes over the rotor and through this changing magnetic field, an eddy current is induced within it. These eddy currents, in turn, create their own magnetic fields that oppose the original magnetic field (Lenz’s Law). This interaction generates a repulsive force that pushes the object away from the magnetic field (Fleming’s Left-Hand Rule).
Inert, non-conductive materials (such as glass, plastic, etc.) simply fall off the rotor due to gravity—their distance thrown is determined solely by the belt speed. In contrast, conductive metal pieces are repelled and thrown farther from the rotor.
A splitter plate is positioned between these two material streams to enable separation. By adjusting the belt speed, rotor speed, and splitter plate position, the Eddy Current Separator can be configured to suit the specific characteristics of the customer’s material.
This was in , when our founder, Mr. Wang, first used magnetism knowledge to make research and designed the first set eccentric pole eddy current separator in China. Thus we are fully aware of this responsibility in sorting resources field for nonferrous metal.
In the year , with 25 years of magnetic experience, Ejet Magnet was Established. Keeping improvement for all kinds of magnetic separators, to provide high-quality and high-performance products is our own responsibility, moreover, offering the best solution and the most effective service is one of the higher-standard targets we are pursuing. Ejet has a strict quality control system for raw materials inspection, producing quality inspection, and machine testing.
