The dewatering screen is a special equipment for the core design of the tailing dry discharge system. The series of dewatering screen has adopted many unique techniques in the design. The method of using multi-frequency vibration for mine dewatering sieve is mainly used. First, it can help the particles in the thicker ore filtration layer to grow from small to large, and from top to bottom to form a thicker layer of ore. Second, it helps filtrate water pass through the filter layer. Third, it helps the cake move forward.
After repeated practice has proved, longzhong has some combination system, such as hydrocyclone and dewatering screen, which is not only a low operation cost, high recovery rate, but also recycles sand.
