Its relative equipments are conveyor, dust remove, draught fan and so on. 

Working Principle

Wet materials are sent into hopper by belt conveyor or bucket elevator, then enter into a large revolving cylindrical tube. The tube has slope slightly so that the discharge end is lower than the feeding end in order to convey materials through dryer. There are many lifting boards which fixed on theinner 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.
