Working principle of Eddy Current Separating Systems

Key feature of the eccentric setup of the Eddy Current system is the self-cleaning mechanism of the magnetic rotor. This results in less wear on the rotor which in turn leads to less downtime of the machine. The large diameter of the Bakker Magnetics eccentric rotor makes sure that, despite of this eccentric execution there is a big angle of magnetic influence for optimal separation results.

The working principle of an eddy current separating system is based on the difference in electric conductivity of nonferrous metals. A conveyor belt leads the product flow towards a magnetic rotor rotating at high speed. This magnetic rotor produces a rapidly alternating magnetic field, causing any nonferrous metals to be ejected from the product flow. Bakker Magnetics rotors utilize radius-shaped magnets to eliminate the excessive air gap, which results in the maximum amount of magnetic force transferred into the nonferrous metals.

Separating ultra fine fractions with Eccentric Eddy Current separator "104"

Bakker Magnetics’ newest Eccentric Eddy Current “104”, is specially designed and engineered for separating fines out of, for example, bottom ashes, electronic waste of small metal fractions. The high speed magnetic rotor inside this machine has the highest number of poles available in the market, 104 (!) and operating at a speed of 3.600rpm the 104 rotor generates an astonishing field frequency of 1.56kHz

Separating course and medium fractions with 12 and 36 pole Eddy Current separator

The 12 and 36 pole separators are suitable for separating course and medium fractions respectively. Use can be found in Municipal Solid Waste (MSW), construction and demolition, wood recycling, plastic recycling, etcetera.

12 Pole is suitable for particles larger than 25mm*
36 Pole is suitable for particles between 5 and 30mm*
