Drying and dry separation combination device as well as dry separation and drying combination device

The invention provides a drying and dry separation combination device, mainly comprising a drying system for drying wet materials and a dry separation system for improving quality of materials by dry separation. In the drying and dry separation combination device, the materials are dried firstly and then dry separation is carried out on the dried materials, wherein a material discharging hole of the drying system is connected with a material feeding hole of the dry separation system through a material conveying mechanism. The application of the device not only organically combines the techniques of selecting coal by a drying process and dry separation so as to show the advantages of drying and dry separation, but also enlarges the application range of the device, has low investment and low production cost and is convenient for promotion and application of the technique for drying and dry separation to improve the quality of coal.
