working principle

The drum dryer drum is a rotating drum that is slightly inclined to the horizontal line. The material is fed from the higher end, and the heat carrier enters from the lower end, and contacts with the material in countercurrent, and the heat carrier and the material also flow into the cylinder together.

With the rotation of the cylinder, the material moves to the lower end under the action of gravity. When the wet material moves forward in the barrel, it receives the heat from the heat carrier directly or indirectly, so that the wet material is dried, and then is sent out at the discharge end through a belt conveyor or a screw conveyor.

The inner wall of barrel is equipped with lifting flight, which can lift the materials and scatter them, increases contact surface of materials and airflow, in order to improve the drying speed and forward the materials advancement.
