If you are always troubled with the agricultural wastes like corn straw, wood flour, wood shavings, saw dust, ginkgo leaf and mulberry leaf, sawdust drying machine must be a good helper for you. We can understand the working principle of sawdust drying machine from the point of classified areas. After the entry into the rotary drum with negative pressure inside, the fully dispersed materials firstly enter into the feeding area. In this area, water content in wet material is rapidly evaporated after contacting with the hot air. Then, under the effect of lifting boards, if the material can not adhere on the boards, the next area would open.

The second area in sawdust rotary dryer is called cleaning area. Inside this area, there is a cleaning device, which can rapidly clean the raw materials that firmly adhere to the wall of rotary drum. Since the cleaning device can also crush the briquette materials, the whole area for heat exchange is widened a lot and the drying speed is accelerated. The third area is called inclined lifting area or cooling area. Since after the above two areas, the raw materials lose the sticking ability. After heat exchange, the water content in finished products is qualified. Then here comes the last area, called discharging area. The finished products naturally slide to the discharging mouth without the help of lifting boards.
