Tailings dry screen is designed basing on high frequency sieve and combining with the characteristics of metal tailings. It is mainly used for iron ore, copper, gold, aluminum ore tailings dehydration dry line. Using tailings dry screen can reduce the occurrence of metal pollution, the pollution and impact on the environment has been minimized. Compared with the wet platoon, the discharge tailings should be less than half the volume, and more importantly, the effective utilization rate of dry tailings pond can reach 100%. The reuse of water has also increased dramatically. Tailings dry line of screen applications make repeated utilization ratio of water reached more than 90%, so the tailings dry screen is of great significance.
