Reasons of Plugging in Use of Polyurethane Screen and Correct Treatment
- 2018-08-18-

Under normal operating conditions, polyurethane screens generally do not exhibit hole plugging during use. If this phenomenon often occurs, it means there is a problem, mainly from the following aspects to check and deal with: 1. Quality of the screen. Screen products with irrational design or substandard quality were selected. When customers choose screen products, they must choose the company's screen products with good qualifications, good reputation and quality assurance. 2. The screen model is not selected properly. After eliminating the quality problem of the screen, the selection of the screen model is very important, and the screen holes cannot reasonably match the diameter of the screened material. Can also lead to the phenomenon of plugging. 3. The humidity of the sieved material is too high. When the material is too large, during the vibration of the screen, the materials are likely to stick together and not easy to separate. Caused the phenomenon of plugging of polyurethane screen. At this time, the material needs to be reprocessed to make it into the screening equipment after the humidity reaches the standard. 4. Improper adjustment of screen tension. If the tension of the screen is adjusted too loosely or too tightly, it will cause the vibration frequency and amplitude of the screen to be insufficient, which will cause the phenomenon of plugging. The treatment method is to regularly check and adjust the tension of the polyurethane screen in a timely manner to adjust it to the technical requirements. 5. Improper material crushing method or breakdown equipment. Causes the broken shape of the material to change (for example, the original round particles become strip particles). Makes the material unable to pass through the screen smoothly. The treatment method is to adjust the crushing method or repair the crushing equipment to meet the requirements of the screening equipment operation requirements. Therefore, as long as you purchase high-quality polyurethane screen products that meet the standards, install and use them properly, and perform regular maintenance and inspection, you can effectively prevent the occurrence of hole plugging in the use of polyurethane screens.
Polyurethane screen is made of rubber material polyurethane screen, which is relatively expensive, while manganese steel screen is woven with manganese steel wire as raw material. The price is relatively cheap. The ore mined in the mine is irregular and the particle size is large. Generally, the crusher is first entered into the crusher. Some materials such as ore are very hard, that is to say, the hardness is high, and some ore materials are low in hardness. According to the softness and hardness of the materials and economic strength, the choice of polyurethane screen or manganese steel screen is used in the current screening environment The best is generally the combination of polyurethane screen and manganese steel screen, taking into account the advantages and disadvantages of both sides, to achieve the purpose of economic and win-win.
