Generally speaking, when sieving particularly fine powders, especially ultra-fine powders, the powder and materials will rub against each other during the sieving process during the feeding process, thereby generating static electricity, causing the materials to agglomerate and suspend each other. Happening. If a general three-dimensional vibrating screen is used, the screen will be severely blocked, the screening efficiency will be severely reduced, and static electricity will also cause the agglomerated materials to float at will, causing material pollution and mixing. Therefore, how to solve the problem of screening static materials has become a headache for customers. Vibrating screen manufacturer-Sanchen Machinery here provides two solutions for everyone:

Method 1: Solve the problem from materials

The direct way to solve the problem of static electricity is to eliminate static electricity. Based on years of experience, Sanchen Machinery provides you with the following solutions:

Connect the ground wire to the screen of the vibrating screen (usually using a three-dimensional vibrating screen) to lead out the current;

Add antistatic agent to the material before feeding;

Increase the humidity of the workshop to increase the humidity of the material. The experiment shows. When the air humidity is lower than 30%, it is conducive to friction to generate static electricity. If the humidity is increased to 45%, static electricity will be difficult to generate.

Method 2: Use ultrasonic vibrating screen to solve the problem fundamentally

Ultrasonic vibrating screen converts 220v, 50HZ or 110v, 60HZ electrical energy into 38KHZ high-frequency electrical energy, which is input into an ultrasonic transducer to turn it into 38KHZ mechanical vibration, so as to achieve the purpose of screening and cleaning. The modified system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen on the basis of the traditional vibrating screen and superimposes a high-frequency and low-amplitude ultrasonic vibrator on the screen. The ultra-fine powder receives huge ultrasonic acceleration. , So that the material on the screen surface is always kept in suspension, thereby inhibiting adhesion, friction, flat drop, and other blocking factors. The material is discharged from the corresponding discharge port to complete the screening work, especially suitable for the screening of ultra-fine materials Minute.

Advantages of ultrasonic vibrating screen:

1. High penetration rate and high screening efficiency;

2. Really solve the problem of screening materials with strong adsorption, easy to clump, high static electricity, high precision and other materials;

3. No bouncing ball and other net cleaning devices are added to avoid secondary pollution of materials and the screen has a long service life;

4. Self-cleaning function, the screen is not blocked.

The above are two methods provided by Sanchen Machinery. If you are still worried about the static electricity generated during the screening of materials, you can use the above methods according to the company's production situation and material characteristics.
