The swing screen, also known as the swing vibrating screen, is a new type of screening equipment that imitates manual screening actions. It can screen cylindrical, strip, and irregular shaped materials. It has the characteristics of large output, high screening accuracy, and does not damage the appearance of the material. It is widely used in food, medicine, chemical, metallurgy and other industries. However, in actual use, after the equipment is started, the material only runs on the screen surface without discharging. What is the reason for this? How should users solve it?

Screen problem

The screen plays the role of carrying materials and screening. The screen of the swing screen usually uses an adhesive structure. When the equipment is in high-intensity operation for a long time, the tension of the screen may be loose, and the screen tension will be insufficient, causing the screen to be wrinkled and uneven. This will cause problems.

Solution to this problem: You can check the tension of the screen regularly. If you find that the screen surface is uneven or the screen is loose, use professional tools to tighten it in time.

2. Blocked screen

The material has certain moisture, viscosity, static electricity and other problems, which will cause blockage during the screening process. Another is that the corresponding mesh size of the screen does not match the mesh size required for the material, which will also cause blockage, resulting in the problem of no discharge.

Solution to this problem: Select a screen with a suitable mesh size. According to the properties of the material, select a suitable screen cleaning device (such as bouncing ball, ultrasonic device, rotating brush).

3. Feeding problem

When feeding materials, if the single feeding amount is too large, or the feed port is not equipped with a distributor, a large amount of material will accumulate on the screen surface, causing the problem of no discharge

Solution to this problem: Install a distributor at the feed port to reduce the screen surface load and play a diversion role on the materials fed. If the feeding amount is large, the silo and discharge valve can be used together to achieve uniform distribution.

The above are the reasons and solutions for the failure of the swing screen to discharge materials. There will be other problems in the use of the swing screen. We can further analyze and provide solutions later.
