Reformation practice of coal slime discharge system in Nanliang colliery coal preparation plant

To solve the problems of the limited stacking capacity,lower space utilization rate and serious environment pollution existed in coal slime discharge system,based on the computer analysis and research,the reformation was conducted on the discharge system.In that reformation,the discharge mode was converted form slime directly falling down from the discharge port into chute discharge which direction can be adjusted.The chute can rotated from three directions at 270° storage the slime,which not only increased the slime storage capacity,but also make the most of utilizing the space,achieved the purposes of reducing the times of cleaning,protecting the environment and increasing utilizing rate of space.
