Polyurethane screen is a vibrating screen with high frequency and high vibration intensity as its main characteristics. It is mainly suitable for wet classification and solid-liquid separation of fine-grained materials below 0.5 mm. So how should you choose a polyurethane screen? Today, the polyurethane screen manufacturer will explain to you:
When choosing a polyurethane screen, look at its appearance: check whether the surface of the polyurethane screen is exquisite, whether the screen is flat, whether the hue of the polyurethane screen is pure, whether there are broken strips, burrs, lack of material, mixing, tight seams, etc. .
Excellent polyurethane screens should be rigid and flexible: In practice, the polyurethane screens must have strong elasticity to ensure that the waist does not collapse during consumption; the polyurethane screens must have certain resistance to ensure that the screens are not fragile.
1. Check whether the sieve holes are uniform: When selecting polyurethane screens, first check whether the sieve holes are uniform: high-quality polyurethane screens have uniform sieve holes and meet the standards, with small tolerances.
2. Appearance: The surface of a good polyurethane screen is flat and the sieve size is uniform; whether the color is pure; whether the edges are neat; whether the edges of the encapsulated screen are neat and uniform. Is there any phenomenon of broken strips, burrs, lack of material, mixing, and tight seams.
3. The screen surface of the screen should be smooth and not rough; use a foot to see the collapse of the screen surface. A good polyurethane screen should have strong elasticity and toughness, that is, the screen should be moderately rigid and flexible. In practice, the polyurethane screens are required to have strong elasticity to ensure that the waist does not collapse during the cost; the polyurethane screens must have certain toughness to ensure that the screens are not fragile.
4. Look at the opening rate: the opening rate is a direct factor that affects the screening efficiency. The higher the opening rate, the higher the screening efficiency and output. Some screen manufacturers extend the service life of the screen and increase its visibility. Deliberately reduce the opening rate.
5. Connection problems, that is, the connection between the screen and the screen during installation, the connection is not good, which affects the screening efficiency. The connection method of the polyurethane screen directly affects the screening power. The polyurethane screens developed by our factory have screens with automatic connection devices. The connection is cumbersome and time-saving, the disassembly and assembly are more convenient, and it is convenient to shorten the initial assembly time and part of the screen replacement time during use, thereby increasing the power consumption. It is requested that the polyurethane screens reach each other tightly and do not leak to ensure the quality.
