Due to the low atmospheric pressure in the plateau, there are high requirements for the air supply equipment of the dry separation system, which limits the application of dry separation technology.

The dry heavy medium shallow trough separator developed by the dry coal preparation engineering technology research center of Shenzhou group in cooperation with China University of mining and technology uses aerodynamics to take a steady-state gas-solid two-phase fluidized bed with a certain density as the separation medium, and sort the coal in the gravity field according to the floating and sinking principle.

In view of the many advantages of the mixed flow drying system and the safety and environmental protection different from the traditional technology brought by its unique drying method, it has become the leader in many mature technologies for upgrading low-grade coal at this stage.

The DDU, dry coal preparation and coal drying system independently developed by the dry coal preparation equipment engineering technology research center of Shenzhou group is applicable to the dehydration and waste discharge of high moisture raw coal, chemical coal and coking coal, so as to greatly improve the calorific value of coal.

In view of the fact that the coal in cold areas cannot be washed and processed in winter, Shenzhou group has developed an alpine dry separation system suitable for coal separation in cold areas. The system adopts special structure and thermal insulation measures to completely solve the problems of coal freezing and pipeline blockage in cold areas.

According to the user's demand for different particle size lump coal separation and the characteristics of lump coal separation, Shenzhou group has developed lump coal dry separation equipment, which has greatly improved the separation effect. At present, it has been widely used in many provincial and municipal coal enterprises in China.

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.
