Rotary dryer is widely used for drying materials with humidity or granularity in the industries of mineral powder , building materials , metallurgy , chemical and so on . Such as sand , coal , sludge , coal slurry , brown coal , fly ash , gypsum , clay , kaolin , slag , rion powder , mill scale , sawdust , chicken manure , feed etc .

Rotary dryer is mainly makes up of revolving body , lifting plate , driving device , supporting device , sealing ring and other components . So it has advantages of reasonable structure , peerfect in workmanship, high yield, low energy consumption, convenient to operation and so on .

Wet materials are sent into hopper by belt conveyor or bucket elevator, then enter into a large revolving cylindrical tube. The tube has slope slingtly so that the discharge end is lower than the feeding end in order to convey materials through dryer. Theer are many lifting boards which fixed on the inner wall of the tube. During drying process, materials are lifting up repeatedly and contact with hot air sufficiently. Then the moisture contained in materials is steamed. At the end of, the waste gas is released into atmosphere by draft fan.
