Amid industry demands for efficiency and sustainability, Binzhou Guxin's modular polyurethane screens are redefining coal washing standards. Featuring mortise-tenon quick-connect with 0.3mm gap control, they eliminate material blockage—reducing daily shutdowns by 4 times and boosting dewatering efficiency 20%. Modular units cut maintenance costs by ¥120K/year through localized replacement, while 50% lighter weight slashes equipment failure rates 27%. The PU material's 40% lower surface tension vs. metal plus 0.5mm micro-textured surface reduces coal slurry moisture from 18% to 13%, saving 15kWh per ton. Nationwide adoption could save ¥450M annually in electricity. With 18-month lifespan in 80°C hot water, they minimize waste and extend green potential to tailings/sludge treatment.
