[0002] As we all know, with the increasing requirements for safe storage of tailings, the tailings classification, concentration and dehydration process has become an important method for tailings treatment. Compared with other tailings dry discharge, it has the characteristics of low operating cost, stable operation and small footprint, and is widely used in tailings dry discharge. During use, the existing tailings dry discharge dehydration screen generally dehydrates and desands the tailings by vibration. A small amount of water and sand adhering to the surface of the tailings will remain, making the dehydration efficiency low. Therefore, we have launched a new tailings dry discharge dehydration screen. Utility Model Content
