    The crushed materials of which the moisture is about 35%-65% are sent into the roller by conveyor to realize downstream drying. Under the effect of the inner shoveling plate, materials are taken and scattered constantly, and move in the spiral forward method. Through three layers (inner, middle and outer layer), heat exchange is realized between material and hot air medium.

Working Principle:

    The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the inner layer of the copy plate to achieve heat exchange in a spiral manner. The material moves to the other end of the inner layer and enters the middle layer. During counter-current drying, the material is continuously raised in the middle layer, showing a two-step forward and one-step travel mode. The material in the middle layer not only fully absorbs the heat emitted by the inner drum, but also absorbs the heat of the middle drum, and at the same time prolongs the drying. Time, the material reaches a dry state here. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in the outer drum in a rectangular multi-loop manner. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not achieve the drying effect cannot be fast due to its own weight. As it progresses, the material is fully dried in this rectangular copy board, thus accomplishing the drying purpose.
