How to Select High Quality PU Screen

PU screen is a kind of high polymer elastic sieve plate, which has excellent wear resistance, oil resistance, hydrolysis resistance, bacteria resistance and aging resistance. The sieve plate can not only greatly reduce the weight of equipment, reduce the cost of equipment, prolong the service life, but also reduce the noise. It should be widely used in vibration sieve washing and grading operations in mining, metallurgy, coal, coke, coal washing, petroleum and chemical industries.

As one of the main parts of screening and sorting equipment, the screen is also one of the vulnerable parts. High-quality screen has the characteristics of wear-resistant, corrosion-resistant, long service life, and users often replace new screen, which can reduce production costs. The screen with poor quality has short service life, and users need to change the screen frequently, thus increasing the production cost. So when you choose the screen, you must choose the high-quality screen manufactured by the regular manufacturer.

Here, we share how to choose high quality PU screen.

1. Eyesight. A good PU screen has a flat surface and uniform screen hole; pure color; neat margin; neat margin of edge-wrapped screen.

2. Touch your hands and step on your feet. Screen surface should be smooth but not rough; when you look at the waist collapse of the screen surface by foot, a good PU screen should have strong elasticity and tolerance, and the screen should be rigid and flexible.

3. Look at the opening rate. The more the number of sieve holes, the higher the opening rate, the higher the screening efficiency and yield.

4. Focus on cohesion. That is to say, the connection between screen mesh and screen mesh during installation is not good, which will directly affect the screening efficiency.
