The Principle of Metal Separator

Our Admin

Metal separators use electromagnetic induction to detect metals. All metals, including iron and non ferrous, it has very high detection sensitivity. When the metal enters the detection area, it will affect the distribution of magnetic lines of force in the detection area, thus affecting the fixed range of magnetic flux. Non ferromagnetic metal entering the detection area will produce eddy current effects, and will also change the magnetic field distribution in the detection area.


Generally, the metal separator consists of two parts, the metal separator and the automatic reject device, in which the detector is the core part. Inside the detector are three sets of coils, the central transmitting coil and the two peer receiving coils. A high frequency variable magnetic field is generated by an oscillator connected by an intermediate transmitting coil, and the induced voltage of both sides of the receiving coil in the idle state is mutually counteracted to reach a balance state before the magnetic field is disturbed. Once the metal impurity enters the magnetic field, the magnetic field is disturbed and the balance is broken, the induced voltage of the two receiving coils cannot be counteracted, and an induced voltage that is not counteracted is amplified by the control system, and an alarm signal is generated. (When metal impurities are detected). The system can use the alarm signal to drive the automatic elimination device so that the metal impurities are removed from the production line.


Types of metal separators: Metal separator is an electronic instrument, it applies electromagnetic induction principle to detect metal, divided into channel type, falling type and pipeline type.


Metal separator application industry:

1. plastics, spices, additives or powder materials are tested prior to further processing to protect subsequent equipment.

2. quality inspection of powder products, such as herbs, tea, milk powder and chemical additives.

3. The food industry, the pharmaceutical industry, and the powder products for both pharmaceuticals and capsules.
