Description

Technical Field

[0002] Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. During the mining process of coal mines, a large amount of coal slime with high water content will be produced. For these coal slimes, it is necessary to transport them from the mine to the ground through a belt elevator for the next step of processing and utilization. The existing technology is not convenient for rapid dehydration of coal slime, which leads to increased pressure during transportation. Coal slime with too high water content cannot be used and needs to be drained before it can be used.
