Rotary drum dryer

The wet material is sent to the hopper by the belt conveyor and enters the drum from the feed port. The main body of the drum dryer is a slightly inclined and rotatable cylinder. When the material enters the cylinder, it is dried by coming into direct contact or countercurrent with the hot air passing through the cylinder, or effectively contacting the heating wall. After drying, the dried material is discharged from the lower part on the other end. During the drying process, the material is dried by the cylinder. The slow rotation, moving from the higher end to the lower end under the action of gravity. The inner wall of the cylinder is equipped with board, which continuously picks up and sprinkles the material, which greatly increases the thermal contact surface of the material, increases the drying rate and promotes the material to move forward. After the heat carrier like hot air and flue gas dries the materials, the entrained dust is collected by the cyclone dust collector and then emptied.
