Principle and application industry of metal separator equipment
Principle of metal separator:
The metal separator is used to detect metal by using the principle of electromagnetic sense. All metals, including iron and non-ferrous metals, have high detection sensitivity. When the metal enters the detection area, it will affect the magnetic field line distribution in the detection area, and further affect the flux of the fixed range. The nonferromagnetic metal will enter the detection area and produce eddy current effect. It will also change the magnetic field distribution in the detection area. Usually, the metal separator is made up of two parts, namely the metal separator and the automatic rejection device, and the detector is the core part. The detector internal distribution of the three groups of coils, namely the central transmitting coil and two pairs of the receiving coil through the transmitting coil connected between the oscillator to generate high frequency variable magnetic field, induction voltage receiving coil on both sides of the idle state are offset in the magnetic field undisturbed before to reach equilibrium. Once the metal impurity enters the magnetic field, the magnetic field is disturbed, the balance is broken, the induced voltage of the two receiving coils can't be cancelled, and the voltage that is not cancelled is amplified by the control system, and the alarm signal is detected (metal impurity is detected). The system can use the alarm signal to drive the automatic elimination device and so on, so as to exclude the metal impurities outside the production line.
Type of metal separator:
A metal separator is an electronic instrument, which uses the principle of electromagnetic induction to detect metal, which is divided into several kinds, such as channel type, falling body type and pipe type.
Metal separator application industry:
1. plastics, spices, additives, or powdery raw materials are tested before the next step, and the follow-up equipment is protected.
2. fine powder products, such as herbal medicine, tea, milk powder and chemical additives, have been tested for quality.
3. the food industry, the pharmaceutical industry, drugs and capsules use fine powder products.
The benefits of using a metal separator:
1. Protection of production equipment
2, improve production efficiency
3, improve the utilization of raw materials
4, improve the quality of products
5, reduce the cost of equipment maintenance and the loss caused by shutdown and maintenance
