Safety of Plastic Metal Separator in Use

- Oct 07, 2019-

The plastic metal separator is mainly made up of the detection part and the rejection part, and the metal sensing principle is applied to detect the metal. All metals, including iron and non-iron, have high detection sensitivity. Ferromagnetic metals entering the detection area will affect the distribution of magnetic lines in the detection area, and then affect the flux in a fixed range. Non-ferromagnetic metals entering the detection area will produce eddy current effect and change the magnetic field distribution in the detection area. When metal impurities pass through, the product alarm signal will be sent to the removal part, and the left-right swing of the turning plate will be removed to eliminate the products containing metal impurities. Thus, the complete separation of metal impurities will be realized.


Safety in use of plastic metal separators:


1. Direction of Use

This equipment is mainly used in plastic industry, but also in food and chemical industry.

This equipment is designed for small aggregated materials (such as powder or granular) that fall freely in vertical pipelines. The import should be connected with hopper or pipeline. This equipment should avoid being surrounded by vapor, dust or similar substances, as this may affect the insulation of PVC wires.


2. Danger Warning

The main power supply is connected to the MSG3.3 electric box, which is connected to the external AC, so there is a danger warning in the door of the electric box.

It is very dangerous to open the cover of the equipment when the power supply is on and the air supply is connected. Secondly, there is a danger warning on the inside of the plastic metal separator.

The height of the inlet and outlet of the plastic metal separator is 80mm, and the hand can easily touch the outlet of the valve.

Cabinet cover protects operators from injury. For repairs or maintenance, please refer to 4.4.

J003

3. Dangers that may arise where there is no warning of danger.

Where there is no warning of danger, there may be static or pneumatic components injuring hands.

Safety precautions for operation and maintenance

When the plastic metal separator is working, the cover and the door of the box should be closed to avoid harm, danger and pollution, and prolong its service life. All warning signs affixed to the machine must be clear and visible, and can not be torn off for any reason. The inlet and outlet should be connected by pipes with a diameter of 70mm. The outlet pipes should be at least 90cm long. If explosive materials are detected, please read the relevant regulations. If the maintenance of electronic and electrical components or pneumatic components is carried out, the power and air sources must be cut off. The operation instructions should be easily accessible and clearly written.

Only trained technicians are allowed to operate and maintain the machine.


5 Potential dangers

After closing the switch, the box may be live because the external power supply is still connected.

In addition, due to the existence of compressed cylinders, after cutting off the air source, the pneumatic components will still operate.


6 unauthorized

No modification or repair work is allowed without authorization of the company.


7 Operations Not Allowed

Operations outside the scope of 1 are not allowed

Operations outside the scope of technical parameters are not permitted.

Detection of corrosive and explosive materials is not allowed
