Most of the machines that screen materials have certain problems in material distribution, output and material recovery. So by upgrading the screen plate of the screening machine, we can greatly reduce maintenance and replacement in later use, and improve the economy. benefit.

1. Traditional sieve plates are prone to wear and tear during use, resulting in screen holes being blocked during the screening process, and the screening rate is low, which has a great impact on the classification and dehydration of the screening machine.

2. If the bolts fixing the screen plate are worn and loosened during use, the screen plate will vibrate with the screen material and continuously hit the screen beam. This will cause excessive fatigue, cracking and other damage to the screen plate.

3. The steel structure screen plate is more likely to cause blockage and damage during screening.

Second, the performance of polyurethane screen plate modification

Regarding the problem of the traditional vibrating screen plate, the polyurethane screen plate is used with a reinforced frame inside to replace the metal screen plate, which overcomes the above problems.

1. The polyurethane screen plate is embedded with a reinforced frame, which can elastically connect the screen beams and effectively prevent the screen plate from loosening.

2. The polyurethane screen plate can produce secondary vibrations during screening, which can effectively prevent the clogging of the screen holes. The screen surface has a relatively strong automatic cleaning ability.

3. The service life of polyurethane screen plates is several times that of metal materials, and its wear resistance is 3-4 times that of manganese steel screens. Therefore, it is wear-resistant, has high strength and has long service life.
