A new gravity & flotation separator with double-tailing discharge and its beneficiation performance

Introduced a new gravity and flotation separator with double-tailing discharge for fine coal, and integrated classification and cyclone scavenging with flotation in an original way. The beneficiation performance of it was good. The results show that the gravity and flotation separator with double-tailing discharge can produce high-quality clean coal of 10.46% ash from fine coal of 35.56% ash. It can discharge the fine and coarse tailings separately.
