Exploration of reducing medium consumption and increasing clean coal yield of dense medium coal separation system in Dushi coal preparation plant

According to the issues that high medium consumption and low clean coal yield and quality in Dushi coal preparation plant,the technical renovation was done on the subsystems such as raw coal deslime,clean coal medium draining,medium recovery in magnetic separation system and clean fine coal medium draining.The result of the technical renovation present not only reduced the medium consumption in production process,but also increased the yield of clean coal,obtained better economic beneficial for the plant.
