Working principleof Recover non-ferrous metals with EddyC

The principle of the eddy current separator is fairly straightforward. Basically, a rotor comprised of magnet blocks, either standard ferrite ceramic or the more powerful rare earth magnets depending on application, are spun at high revolutions (over 4000 rpm) to produce an 'eddy current'. This eddy current reacts with different metals, according to their specific mass and resistivity, creating a repelling force on the charged particle. If a metal is light, yet conductive such as aluminum, it is easily levitated and ejected from the normal flow of the product stream making separation possible. 
These systems use the latest and most effective magnetic circuits to produce strong eddy current forces, which maximizes efficient separation. Also incorporated are proven design features, such as quick and easy machine adjustments, single source dependability, and energy efficiency.

The frequency of the ecs rotor is critical to ensure that good separation is achieved. This is made possible by its precisely adjustable separating splitter mechanism, optimised to the drop parabola of the material stream.This is why we have developed a rotor specifically for can sorting that has the maximum number of poles and rotates at the optimum speed to give the best and most selective separation of aluminum cans. 

EJET`s whole metal recycling equipment to separate metal scraps and waste 

1.Shredding/crushing system 

The shredding of metal scrap represents the first step in the recycling cycle, regardless of whether the metal scrap comes from the metalworking industry, automotive industry, electrical industry or waste industry. Typical applications include punching waste, beverage cans, profiles, car body parts, sheet metal waste and aluminum scrap of all kinds.

2.Air classification machine :

in a shredder system commonly designed for vehicles, the shredded material is subjected to air separation before the separation of steel and iron material. This creates a light fraction capable of flight, known as the shredder light fraction (SLF). The heavy items from the air separation is - after separation of iron - the shredder heavy fraction (SHF). Air classifiers are commonly employed in industrial processes where a large volume of mixed materials with differing physical characteristics need to be separated quickly and efficiently.

3.Trommel screen :

or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. The mesh holes are arranged from small to large, and the mesh hole diameter on each section is the same.

2.Magnetic Separation System :the model selection depends on the ferrous content.it is may be a suspension overband magnetic separator ,a drum magnetic pulley or just a magnetic plate can fulfil the task for Magnetic metal recovery

4.Eddy current separator :

The principle of the eddy current separator is fairly straightforward. Basically, a rotor comprised of magnet blocks, either standard ferrite ceramic or the more powerful rare earth magnets depending on application, are spun at high revolutions (over 3000 rpm) to produce an 'eddy current'. This eddy current reacts with different metals, according to their specific mass and resistivity, creating a repelling force on the charged particle. If a metal is light, yet conductive such as aluminum, it is easily levitated and ejected from the normal flow of the product stream making separation possible. .

eddy current separators commonly used to separate non-ferrous metals from mixed waste and other product streams. When a magnetic rotor is turned at high rates of speed, powerful forces called eddy currents are created.
These eddy currents repel materials with varying degrees of force depending on their composition. Thus, able to separate and recover aluminum and other non-ferrous metals from household, industrial and incinerated waste, including inert plastics and other materials. It is able to separate metals from scrap, and remove metallic particles and contaminants from glass and other substances. In fact, eddy current separators offer a cost effective method of recovering up to 95% of valuable material from rubbish and waste, grading precious metal concentrates for further processing. It also improves the purity of non-ferrous auto scrap up to 85-95%, maximizing the speed and efficiency of recovery and increasing profits.

5.Induction stainless steel sorter  

Induction sorter is detecting the inductive metal such as copper , aluminum, Zinc, Lead,  stainless steel, print circuit board(PCB) and insolation wire etc through the imbed induction sensor under the belt. With high pressure valve connected one line of nozzle after the high speed belt, eject those detected objects, the inductive of sensor could be adjusted through software via the screen.

It is normally being installed after eddy current in order to recover rest of metal after eddy current sorting such as copper, brass, zinc, aluminum and those could not be sorted by eddy current as stainless steel and insolation wire etc.
