The scheme adopted for optimization of the dense medium separation system and effect obtained at Hongyang No. 2 Mine Coal Washery

The washery is facing the problems of high consumption of medium per ton of coal treated and low separation accuracy of H.M.cyclone.Based on the result of analysis of the current operation status and in line with the specific conditions of the washery,a series of measures is taken to optimize the dense-medium separation system.Through repeated optimization efforts,a remarked result has been obtained as evidenced by the reduction of medium consumption from 3.06 kg to 1.55 kg,a drop of clean coal ash by 2 percentage points and increase of total yield of clean coal by 2.36 percentage points.
