reasons and correct treatment of polyurethane mine screen in use

Under normal operating conditions, polyurethane mine screen generally does not appear in the course of the phenomenon of clogging. If this happens often, it means that there is a problem, mainly from the following aspects of the inspection process：

1.Screen quality problems. Selection of the design is not reasonable or the quality of the screen products. When customers buy mesh products, to choose a good quality, good reputation, quality assurance of the company's mesh products.

2. Screen model selection is not appropriate. After the exclusion of the quality of the screen, the screen model selection is very important, the sieve cannot be a reasonable match with the diameter of the screening material. It will lead to the occurrence of the phenomenon of plugging holes.

3. The humidity of the sieved material is too large. When the material is too large, the screen vibration process, prone to adhesion between materials, not easy to separate. Resulting in a polyurethane mine screen clogging phenomenon. Then the need for material reprocessing, so that the humidity standards and then put into the screening equipment.

4. Screen tension adjustment is not appropriate. Tension adjustment of the screen is too loose or too tight, will lead to insufficient vibration frequency and vibration amplitude of the screen, which occurred clogging phenomenon. The processing method is to regularly check and adjust the tension of polyurethane mine screen, adjusted to the technical requirements of the range.

5.Improper material crushing method or crushing equipment failure. Cause the material to change the shape of the broken (for example, the original round granular particles into strips). So that the material can not pass through the sieve. The processing method is to adjust the crushing method or repair crushing equipment to meet the requirements of the screening equipment operating conditions.

Therefore, as long as the purchase of standard high-quality polyurethane mine screen products, correct and reasonable installation and use, regular maintenance and inspection, can effectively prevent the occurrence of the phenomenon of polyurethane mine screen hole blocking use.
