The dry preparation technology of fine coal breaks through the technical bottleneck of high lower limit of dry preparation, further optimizes the bed structure and air distribution system, greatly improves the separation effect, and provides a new technical way for processing and quality improvement of end coal that cannot be washed.

Features:

●Optimize the bed structure and air distribution system to reduce the lower limit of effective separation.

●The operation cost is low, which completely solves the problems of water washing of fine coal and difficult treatment of slime water.

●The design of dust removal system is more scientific and efficient.
