HZG Rotating Cylinder Dryer
1.Working principle
After the dame raw material is put into the drier by feeder,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 accelerate heat and mass transfer.It is simple in structure,convenient in maintenance
2.Application
1 It is suitable for drying raw materials .For example:ore,slag of blast furnace,coal, and so on.
2 It is suitable for the material which need cooling,and need large quantity continuous operation.
3 Heat resource used:electricity,stream,heat pipe ,furnance or waste heat.
