The beneficiation and special material screening line is designed for complex materials such as metal ores, non-metallic ores, wet viscous and fine particles. It uses high-efficiency screening equipment such as high-frequency screens and banana screens to achieve precise classification and dehydration and desliming. This solution effectively solves problems such as hole blockage and coarsening, and improves the recovery rate and concentrate grade of mineral processing. The structure is wear-resistant and corrosion-resistant, suitable for harsh working conditions such as heavy media and strong impact, and widely used in fields such as iron ore, phosphate ore, and tailings dry discharge.
