Study on the Transformation of Shallow Trough Gangue Discharge and Coarse Slime Separation System

This paper expounds the necessity of the transformation of the shallow channel gangue discharge and the coarse slime separation system in Tunlan Coal Preparation Plant,and analyzes the reformed content and main applied equipment of the system.After transformation,the practical application effect is ideal.The technological indexes such as the proportion of the large gangue with coal,the washed raw coal ash,the loss of medium coal,the yield of coarse and fine coal slime,and the raw coal washing capacity of dense medium system are good,and the productivity is increased,which brings better economic benefits for the enterprise.
