[0002] The drum dryer is a traditional drying equipment, primarily consisting of a rotating body, a lifting plate, a transmission mechanism, a support mechanism, and sealing rings. The dryer is a cylinder slightly tilted from the horizontal. Material is fed into the cylinder at the higher end. High-temperature flue gas generated by the heating equipment flows into the cylinder along with the material. As the cylinder rotates, gravity forces the material to the lower end.
