Electric selection equipment

The electroselective device is based on the electrostatic force applied to the temporarily charged particles. The design of the electric separator is based on the mineral belt motor. According to the motor, the electric sorter can be divided into the following three categories:

1) Free fall electrostatic sorter (contact charging and triboelectric charging);

2) High voltage electric separator (corona charging);

3) Contact the electric separator (inductive charging).

(1) Contact or friction electrification electric separator (free fall electric separator)

In such an electric sorter, an electric charge is obtained by contacting or rubbing between particles or with a third material such as a vessel, a feeder, a chute or a wall of a nozzle. These particles then enter the electric field and separate according to their polarization and the amount of charge carried.

(2) Conductive induction charging electric separator

When the particles are in contact with the conductive electrode, the conductor can be separated from the non-conductor in the electric field, which is the basis of the conductive electric separator. When a high voltage electric field is present, different particles are in contact with the ground conductor, and conduction induction charging can occur. Usually, by conduction, the conductor particles are rapidly charged, and the insulating particles are charged much more slowly, thereby separating the conductor particles from the insulating particles.

Nowadays, many companies like to buy PVC soft-curtain high speed rolling doors when purchasing PVC fast-rolling doors. What are the characteristics and advantages of it that make everyone love it? Let's talk about the overall advantages of PVC fast roller shutter doors.

Features and advantages of PVC fast roller shutter doors:

1.Good UV protection effect of PVC fast roller shutter door

The UV-proof door curtain of PVC fast rolling door, as the screen of the welding welding area, can filter harmful UV rays through the scenery, which is convenient for viewing the working situation, and prevents the flying and diffusion of sparks, smoke, debris, etc., to protect the safety of personnel. prevent fire.

Sound insulation effect PVC fast roller shutter door curtain can reduce noise decibels, prevent noise diffusion, reduce noise pollution, and be used as a machine compartment screen to improve the sound insulation effect of operations.

2. Good cold resistance effect of PVC fast roller shutter door

In the case of low temperature, the PVC fast rolling shutter can still maintain a high degree of softness, making it convenient for people and vehicles to enter and exit, and has a good isolation effect. It can prevent the loss of air conditioning and heating to a greater extent and save energy.

3. Good airtight performance of PVC fast roller shutter doors

A sealing strip with better sealing performance is installed in the track of the fast roller shutter door. With the weight of the door curtain itself, it will not bend and affect the normal operation under the wind speed of the harsh weather.

4. Good thermal insulation and energy saving effect of PVC fast roller shutter doors

PVC fast rolling shutter not only consumes no electricity, has no noise, no moving components, improves freezing efficiency, but also reduces the number of revolutions of the freezer, saving up to 50% of electricity.


5. Good anti-static effect of PVC fast roller shutter door

The curtain of the PVC fast rolling door does not produce static electricity after friction, which is suitable for the factory effect where static electricity is strictly prohibited.

Widely used in office buildings, public buildings, hotels, hospitals, supermarkets and factories in Asia, Eastern Europe and Africa. The specific requirements of an effective door system in different situations (eg clean room, operating room) may vary in different parts of the world.
