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.
The rotary dryer is suitable for drying wood chips, sawdust, bamboo chips, wood powder, wood pieces, wood shavings, rice straw, wheat straw, corn straw, sorghum straw, maize silage, and potato vines, beanstalks, and so on. The equipment has the advantages of large output, high efficiency and energy saving, small occupation area, energy-saving, and cost-saving.
