Polyurethane slotted screens have always been favored by the majority of screening machinery manufacturers and users for their wear resistance, light weight and long life. The crushing, frame selection and screening work environment is very harsh, with a lot of dust, high humidity, high noise, very large processing capacity, and hard ores, especially the screens and sieving plates of vibrating screens, which are the main working surfaces for material screening. It not o原来必须承受联合国矿石的巨大影响loading from the feeding end, but also withstand the load of the ore and mechanical vibration (including secondary vibration). This requires the screen to have very high wear resistance and endurance, polyurethane slits The screen is a very good choice.
