Material Source: The core material of polyurethane circular vibrating screens is high-molecular-weight polyurethane (PU), a polymer material synthesized from polyols and isocyanates through a chemical reaction. Polyurethane raw materials are typically derived from petrochemical products, such as petroleum-derived polyols and isocyanates, and the hardness, elasticity, and wear resistance of the material can be adjusted through different formulations and additives. Through precise proportioning and polymer synthesis technology, polyurethane materials with stable performance and suitable for screening applications can be obtained.
Manufacturing Source: Polyurethane circular vibrating screens are generally produced by specialized screen manufacturing companies. Through injection molding, casting, or compression molding processes, polyurethane materials are processed into a screen with an integrated screen surface layer and support layer. During the production process, reinforcing fillers or functional additives are also added to improve wear resistance and corrosion resistance. Large screening machines often adopt a modular design for easy installation and replacement.
Industry Application Background: Polyurethane circular vibrating screens originated from the need to improve the insufficient wear resistance and easy clogging problems of traditional metal screens. In industries such as mining, building materials, chemicals, and food, metal screens are prone to wear and deformation under high-frequency vibration and impact from hard materials. Therefore, polyurethane screens have emerged as a solution. With advantages such as lightweight, high elasticity, wear and corrosion resistance, and modular design,
