Rotary Drum Dryer Working Principle

The rotary dryer cylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into the rotary dryer cilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in the rotary dryer cylinder body, the lifting plates inside the rotary dryer cilinder makes the Get price
