Non Magnetic Metal Sorter / Eddy Current Separator / Eccentric Poles Position

Product Overview

Description

Eccentric Pole Eddy Current Separator for Solid Waste Sorting Introduction: 

 CHNMAG Eddy Current Separator separates nonferrous metals such as aluminum, die-cast metal, and copper from nonmetallic material.

Solid Waste Sorting Machine - Eccentric Pole Eddy Current Separator Features:

 The Eddy Current separator separation results can be affected by the following factors

• magnetic rotor speed

• magnetic rotor angle setting

• belt speed

• strong and deep magnetic field

So we optimize our design accordingly

• magnetic rotor speed - 0-3000rpm rotation speed

• magnetic rotor angle setting - manually adjustable rotor position in drum shell 

• belt speed - adjustable speed motor drive

• strong and deep magnetic field - high grade NdFeb magnet system with multiple poles in rotor 

 

 Working Principle:

 

Material is fed onto the conveyor belt of the eddy current separator, which moves it across the magnetic rotor where separation occurs. The magnetic rotor is surrounded by (but not attached to) a wear shell which supports the conveyor belt. This allows the rotor to spin independently and at a much higher speed than the wear shell and belt. When a piece of nonferrous metal, such as aluminum, passes over the separator, the magnets inside the rotor rotate past the aluminum at high speed. This forms eddy currents in the aluminum which in turn create a magnetic field around the piece of aluminum. The polarity of that magnetic field is the same as the rotating magnet, causing the aluminum to be repelled away from the magnet. This repulsion makes the trajectory of the aluminum greater than that of the non-metallic, allowing the two material streams to be separated.

Advice:

CHNMAG Overband Magnet, Magnetic Pulley, Magnetic Drum are recommended prior to the eddy current separator.

An eddy current separator is NOT designed to be a source of magnetic ferrous separation. Serious damage will occur if magnetic separators such as pulleys or drums are not used to remove the ferrous metal from the burden before it reaches the eddy current system. At least two stages of magnetic separation.
