Rotary double drum dryer

Overview: The double drum dryer has made significant breakthroughs and innovations on the basis of the traditional single drum rotary dryer structure 1. Double tube dryer has high thermal efficiency and significant energy-saving effect 2. The material exchanges heat with the hot air flow in the inner cylinder through radiation, convection, and conduction, while in the outer cylinder, heat exchange is carried out through a combination of conduction and convection 3. The shortened length of the machine is beneficial for process layout. The overall...
