Abstract：

In order to improve the separation proportion of steam coal,introduce the separation features. Optimize process of separating steam coal by the contrasting dry coal preparation,discharge of refuse by jigging,discharge of refuse from lump coal by dense medium separation without small coal feed,three products H. M. cyclone separation of all raw coal and discharge of refuse by H. M. vessels and cyclone.It is necessary to select energy-efficient and water saving equipment with large capacity of unit to reduce cost of production and capital investment. Provide that large-scale,efficiency,generalized and modularization is the development tendency. Introduce large-scale efficient packaged technologies and key equipments used for the separation of lump coal,slack coal and fine coal in ten-million-ton steam coal separation. Meanwhile,develop matching large-capacity sizing crusher and medium drainage or dehydration equipments.

Key Words： steam coal;separation;slack coal;large-scale
