Three Cylinder Rotary Dryer

The three-cylinder rotary dryer is composed of three cylinders. the material is swirled through three cylinders to fully utilize the heat to dry the material to the specified moisture requirements.

Equipment Principle: The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting plate in the inner layer to realize heat exchange in a spiral manner. The material moves to the other end of the inner layer and enters the middle layer for countercurrent drying. The material is continuously pushed forward in the middle layer in a two-step forward and one-step back motion. The material in the middle layer fully absorbs the heat emitted by the inner drum, but also the heat of the middle drum, while prolonging the drying time, achieving the optimal drying state of the material.

The material travels to the other end of the middle layer and falls into the outer layer. The material movess in a rectangular multi-loop manner in the outer drum. The material that reached the drying effect travels quickly and is discharged from the drum under the action of hot air. The wet material that not reached the drying effect cannot be quickly moved due to its own weight. the materials are fully dried in this rectangular lifting plate to achieve the drying purpose.

Three cylinder sawdust rotary dryer applies for a variety of powder materials, such as sawdust, powder, rice husk, wood shavings, etc.
