Description

Coal Slime Slurry Plant

technical field

The utility model relates to the technical field of coal equipment, in particular to a coal slime pulping device.

Background technique

At present, a by-product coal slime is produced during the coal washing process, and the coal slime becomes a coal slime filter cake after being dehydrated by a filter press.
