As one of the main parts of the screening and sorting equipment, the polyurethane sieve plate is also one of the wearing parts. High-quality sieve plates are very wear-resistant, corrosion-resistant, and have a long service life. Users often replace new sieve plates and can reduce production costs. The inferior sieve plate has a short service life, and users need to replace the sieve plate frequently, thereby increasing production costs. Therefore, when you choose a sieve plate, you must choose a high-quality sieve plate produced by a regular manufacturer. So how to choose high-quality polyurethane sieve?
1. Eye view. The surface of a good polyurethane screen is smooth, the size of the screen hole is even; the color is pure; the margin is neat; the edge of the screen mesh is neat and uniform.
2. Touch by hand and foot. The screen surface of the screen should be smooth and not rough; use your feet to look at the collapse of the screen surface. A good polyurethane screen should have strong elasticity and resistance, and the screen should be moderately rigid and soft.
3. Look at the porosity. The more the number of screen holes, the higher the opening rate, the higher the screening efficiency and output.
4. Pay attention to the connection. That is, the coupling between the screen and the screen during installation. If the coupling is not well connected, it will directly affect the screening efficiency.
Polyurethane screens and sieve plates are commonly known as beef tendon screens. They are produced by high-quality polyester polyol synthetic casting and high-temperature vulcanization. Polyurethane sieve plate belongs to mining equipment and is used in mining and quarrying plants in combination with vibration screen and other mining equipment. Widely used in coal plants, mines, petroleum, chemical industry, construction, machinery accessories, can be used as a grading screen for solid materials, used as a screen, for liquids and mud.
Classification of polyurethane screen
Classification: Polyurethane dewatering screen plate and polyurethane slit screen plate
Is divided into four types according to the structure of polyurethane screen:
1) Mosaic type
2) Bolt connection
3） Bead connection
4) Screen hook connection
Advantages of polyurethane screen
1. Long service life and large carrying capacity.
2. High screening efficiency.
3. Wide range of application, stronger professional applicability, suitable for any type of vibrating screen machine and can be made by measuring machine.
4. High screening accuracy.
5. The working noise is low, which meets the environmental noise standards of national specifications.
6. Significant economic benefits.
