Metal separator | Plastic particle metal separator | Pipeline metal separator

1、 Product Overview

The metal separator applies the principle of electromagnetic induction to detect metals. All metals including iron and non-ferrousAll have high detection capabilitiesSensitivity.

The entry of ferromagnetic metals into the detection area will affect the distribution of magnetic field lines in the detection area, thereby affecting the magnetic flux within a fixed range.

Non ferromagnetic metals entering the detection area will generate eddy current effects and also cause changes in the magnetic field distribution in the detection area

Mainly used for detecting loose granular materials (particles<8mm) fed by gravity, it can be used in the plastic industry, food industry, chemical industry, etc.

The hazards of metal impurities in product forming:

1. In terms of injection molding: damaged screw Scratch the cylinder block Block the nozzle.

2. Regarding the mold: Scratching the mold Block the mold flow channel.

3. In terms of products: The finished product contains metal, which causes short circuits and insulation, and scratches the surface of the product.

4. In terms of crushing processing: Damaging the crushing blades leads to more metal fragments.

2、 The principle of the product

Usually, a metal separator consists of two parts, namely a metal separator and an automatic removal device, with the detector as the core part.

There are three sets of coils distributed inside the detector, namely the central transmitting coil and two equivalent receiving coils. The high-frequency variable magnetic field is generated by the oscillator connected to the transmitting coil in the middle. In the idle state, the induced voltages of the two receiving coils cancel each other out before the magnetic field is disturbed, reaching a balanced state. Once metal impurities enter the magnetic field region and the magnetic field is disturbed, this balance is broken, and the induced voltage of the two receiving coils cannot be cancelled out. The un cancelled induced voltage is amplified and processed by the control system, and an alarm signal is generated (metal impurities detected).

The system can use this alarm signal to drive automatic removal devices, etc., to remove metal impurities from the production line.

3、 Product features:

1. It can detect and separate magnetic and non-magnetic metals, avoiding the impact of metals on production equipment and product quality in subsequent production processes.

2. It can effectively solve the problem of non-ferrous metals (such as copper, stainless steel, lead, aluminum, etc.) that cannot be attracted by magnets, solving the problem of metals for customers.

3. It can be directly installed at the feeding port of injection molding equipment or used separately.

4. The special removal structure ensures fast and accurate separation of metal particles.

5. Plastic widely used in free fall environments. Food. Chemical and other industries.

4、 Product performance
