What are the Classifications of Polyurethane Mesh Screen?

Vibrating screen is the indispensable main equipment in mineral processing and classification operation. Its specifications and models are diverse in order to meet the different classification and dehydration purposes, and the sieve structure, size, sieve hole size and distribution are various.

Screen surface is usually assembled by several screens. Traditional screens are usually made by punching, braiding or tailor welding. The material is carbon steel, stainless steel or alloy steel. The screen mesh is seriously impacted and worn by ore, and the frequency of the vibration screen is high, which makes the weld easy to fatigue and crack, so the service life of the screen is short and the replacement is frequent, seriously affecting the production efficiency of the vibration screen.

Polyurethane elastomer products have the properties of wear resistance, oil resistance, aging resistance, tear resistance, impact resistance, high elasticity, strong vibration absorption and large load support capacity. The polyurethane mesh screen has the characteristics of light weight, high screening efficiency, no easy plugging holes, wear resistance, impact resistance and long service life, which has been widely used in vibration screen of the industries such as metallurgy, mining, coal and so on.

Classification of Polyurethane Mesh Screen

Polyurethane mesh screen can be divided into dehydration screen, de-intermediation screen and material grading screen according to its use; polyester screen or polyether screen according to its raw material composition; and fastening screen, bolt screen and tension screen according to the fixed mode of vibration screen.
