HUATAO GROUP's polyurethane screen panels are specifically engineered to address the unique challenges of coal processing operations. Our solutions combat extreme abrasion from coal and shale, prevent blinding caused by moisture and clay, and enhance workplace safety through lighter weight and non-sparking properties. With proven results including 8x longer lifespan than steel screens, 15% increased processing capacity, and 40% reduction in maintenance costs, HUATAO provides reliable, efficient screening solutions for coal preparation plants worldwide. This article details how our specialized polyurethane technology delivers tangible improvements in efficiency, cost reduction, and safety for coal mining operations.

In the industrial screening industry, frequent screen plate replacements can cost millions annually in downtime. Polyurethane rubber screen plates, thanks to their unique molecular structure, extend their service life to 3-5 times that of metal screen plates. They also achieve self-cleaning through elastic vibration, boosting wet and sticky material screening efficiency to over 85%. This article provides an in-depth analysis of their four core advantages:

❶ Superior wear resistance: The hard/soft segment microphase separation structure creates a "wear-resistant fortress," with a Shanxi coal mine demonstrating a service life increase from 2 months to 8 months.

❷ Impact-resistant design: An 80MPa elastic modulus absorbs 80% of impact energy, withstanding impacts from 300mm iron ore.

❸ Precision production process: High-pressure casting technology controls the bubble rate to <0.1%, and nano-silicon carbide additives improve wear resistance by 20%.

❹ Proven economic benefits: The mineral processing line saves 240,000 yuan in annual procurement costs and reduces downtime by 1.68 million yuan.

In the field of precision wet screening of silica sand, traditional metal screen mesh severely restricts production efficiency due to frequent replacement, metal fatigue fracture, and efficiency degradation. This article is based on USGS 2023 data and reveals how the top 5 countries in global silica sand production (the United States, China, Italy, Germany, Australia) and top mining companies (such as Sibelco, Covia) optimize production through polyurethane sieve plates.
