Coal single drum dryer is a specialized equipment for drying materials in the coal industry, mainly used for drying coal slurry, raw coal, flotation clean coal, mixed clean coal and other coal materials. It consists of a heat source, a dispersing device, a belt feeder, a feeding machine, a rotary drum, a belt discharge machine, a induced draft fan, an unloader, and a distribution cabinet.

Working principle

The working principle of a coal single drum dryer is to use hot air or flue gas as a heat carrier, which comes into contact with wet materials and uses the heat to dry water vapor, achieving the purpose of drying the materials. Wet materials are added from the high end of the equipment and flow towards the low end. During the process, the plate inside the cylinder continuously lifts the materials, and the heat carrier comes into contact with the materials in a forward or backward flow, completing the drying process.

Application area 

Coal single drum dryer is widely used in the drying of materials in the coal industry, such as coal slurry, raw coal, flotation clean coal, mixed clean coal, etc. In addition, it can also be used for drying materials such as blast furnace slag, clay, bentonite, limestone, quartz, etc. in the construction industry; Drying of metal concentrates, waste residues, tailings and other materials in the mineral processing industry; And the drying of non heat sensitive materials in the chemical industry.
