Polyurethane screen panel is a kind of reticulated product produced with polyurethane as raw material, as long as it is used in mine mineral processing, classification, dehydration and other screening machines to replace metal sieve plate (net). Polyurethane screen panel is mainly used in coal mine, iron ore, copper ore, and other ore classification, screening, dehydration and other places, is one of the necessary accessories of vibrating screen. According to the screen holes, polyurethane screen panels are divided into slit, rectangular, circular and square screen panels. The friction coefficient between polyurethane and material is low, and because the service life of polyurethane screen panel is 3-5 times longer than that of stainless steel sieve plate, and the number of maintenance and replacement is less, it is the preferred choice in many industries. Polyurethane screen panel is wear-resistant, moisture-resistant, can work under the condition of water medium, has a long service life, and can avoid the adhesion of wet particles, which is more than 5 times that of ordinary rubber screen panel.
