Study and field application of the methods for reduction of medium consumption at Hecaogou Coal Preparation Plant

In order to tackle the problem regarding the considerably high consumption of medium, work is made by the plant on optimization of the medium recovery system through improving the material spreading box of the sieve bend and adjusting the angles of water spray of the medium draining screen and the magnetic separator. Practice shows that the use of the renovated and optimized system has led to an overall cut of consumption of magnetite powder by 0.4 kg/t, a rise of economic revenue by 700 000 yuan, an increased recovery of magnetic material, reduced operating cost and a favorable economic result.
