Anti-blocking screens are high-efficiency screening media designed specifically to address common blockage problems during material screening, and have a unique self-cleaning function. Its core structure uses highly elastic polyurethane strips to fix independent manganese steel wires, and achieves automatic cleaning through high-frequency vibration, effectively avoiding blockage and improving screening efficiency and cleanliness. The current mainstream anti-blocking screens include diamond-shaped holes, corrugated holes, and triangular holes, each of which is suitable for different material characteristics and screening scenarios. This article will systematically introduce the anti-blocking principles, structural characteristics, applicable scenarios and advantages of various anti-blocking screens, and provide a reference for the selection of screening equipment in the mining, building materials, metallurgy and other industries.
