In mining operations, selecting the right screen mesh is critical to achieving high screening efficiency and controlling operational costs. A one-size-fits-all solution simply does not work—different ores require different materials, structures, and aperture designs based on their hardness, moisture content, particle size, and abrasiveness.

For hard and highly abrasive materials such as iron ore, heavy-duty meshes like high manganese steel or perforated plate screens provide excellent impact resistance and extended service life. In contrast, wet and sticky ores such as copper and gold benefit significantly from polyurethane (PU) screen meshes, which offer anti-clogging performance and 3–5 times longer wear life compared to traditional metal screens.

Coal processing presents another challenge due to high moisture and fine particles. High-frequency polyurethane screens or self-cleaning PU meshes are ideal for maintaining throughput and reducing downtime. Meanwhile, ultra-fine mineral classification, such as tungsten slurry, requires multi-layer high-frequency PU screens to ensure precise separation and higher concentrate grades.
