    Woodchips Drum Dryer application

    Rotary drum dryer, with wide application and easy operation, is widely used to dry sawdust and woodchips in biomass pellet industry. Hot air or gas convey heat to the material and evaporate wood chips. By renewing drying media inside the dryer, and together with the function of ventilation, moisture of the raw material will be get rid of. Convection drying in the dryer can dry the material. The barrel of rotary dryer is single drum type. The body of dryer is installed horizontally with the ground. Material feeding at the feeding end, with rotation of dryer and aeration, the material flows to the discharge end. Shoveling plate equipped in the dryer make the material moving forward. In biomass industry, the length of dryer is around 6-20m. Such length is to guarantee the stay time of material inside the dryer. Heat exchange is carried inside the dryer between hot air and material.

     Operation principle

    Driving chain of main reducer and chain wheel drive the driving shaft, friction gear installed on the driving shaft mesh with the friction ring and operate in opposite direction. Hot air generated by stove (match with equipment) induces into the dryer by fan. The material inside the dryer is turned up by the plate installed on the wall of dryer to achieve the even drying. The dried material discharge from the discharge gate. With the continuous rotation of motor, material continuously goes into the following production.
