The mechanization content of rotating drier is high and its productive capacity is large.
Because the resistance when fluid passes through the cylinder is small, the consumption of power is low.
Have strong adaptability to raw materials.
Its operation is constant and its operation cost is cheap. The homogeneity of dried product is good.
工作原理 WORKING PRINCIPLE：
濕物料從干燥機一端投入后，在內筒均布的抄板器翻動下，物料在干燥內均勻分布與分散，并與
并流（逆流）的熱空氣充分接觸，加快了干燥傳熱、傳質推動力。在干燥過程中，物料在帶有傾斜度
的抄板和熱氣流的作用下，可調控地運動至干燥機另一段星型卸料閥排出成品。
After the damp raw material is put into the drier from one end, it is turned over through stirring-up rake inside the cylinder and distributed uniform in the drier and contacted with countercurrent hot air fully. It speeds up heat and mass conducting of dry. During the period of dry, raw material is effected by stirring-up rake with gradient and hot air, it can be moved and passed through the dry region and to star valve and then discharge the finished product.
It is suitable for drying raw materials that have large size and heavy specific gravity. For example: ore, slag of blast furnace, coal, metallic powder, phosphorous fertilizer, ammonium sulphate and so on.
Dry powder, granule raw materials which have special requirements to drying. For example: HP vesicant, lees, light calcium carbonate, active white earth, magnetic powder, graphite, medical slag and so on.
Dry raw materials the need to dry at low temperature continuously and its batch is large.
