Anti-sticking and Corrosion Resistance Requirements for Woven Mesh Used in Compound Fertilizer Granules Screening‌

Most blends have things like urea and ammonium nitrate, which grab moisture from the air and form a tacky surface. So, as soon as these granules hit an ordinary woven metal mesh, they start gluing themselves down. Before long, you’ll have a solid cake blocking your screen. The answer is to use a mesh that doesn’t let particles cling in the first place. Polyurethane or rubber-coated meshes work well because their slick, water-repellent surfaces make it hard for granules to hang on. If you’re set on using metal mesh, go for one that’s been polished smooth or coated with something truly non-stick, like PTFE, so you still get that easy-release surface.
