Under normal working conditions, polyurethane screens generally do not block holes during use. If this phenomenon occurs frequently, it means that there is a problem, and it should be checked and handled mainly from the following aspects:

1. Quality problems of the screen. Screen products with unreasonable design or substandard quality are selected. When customers purchase screen products, they should choose screen products from companies with good qualifications, good reputation, and guaranteed quality.

2. Improper selection of screen models. After eliminating the quality problems of the screen, the selection of screen models is very important, and the screen holes cannot be reasonably matched with the diameter of the screened material. It will also cause blockage.

3. The humidity of the screened material is too high. When the material is too large, the materials are prone to adhesion and are not easy to separate during the vibration of the screen. This causes the polyurethane screen to block holes. At this time, the material needs to be reprocessed so that the humidity meets the standard before being put into the screening equipment.

4. Improper adjustment of the screen tension. If the tension of the screen is adjusted too loosely or too tightly, the vibration frequency and amplitude of the screen will be insufficient, resulting in blockage. The solution is to regularly check and adjust the tension of the polyurethane screen in a timely manner and adjust it to the range of technical requirements.

5. Improper material crushing method or crushing equipment failure. The crushed shape of the material changes (for example, the original round particles become strip particles). The material cannot pass through the screen hole smoothly. The solution is to adjust the crushing method or repair the crushing equipment to meet the operating requirements of the screening equipment.

Therefore, as long as you purchase high-quality polyurethane screen products that meet the standards, install and use them correctly and reasonably, and perform regular maintenance and inspections, you can effectively prevent the occurrence of blockage during the use of polyurethane screens.
