Structure of Rotary Dryer:
A rotary dryer machine is mainly composed of cylinder, front roller ring, back roller ring, gear, catch roller, riding roller, pinion, discharging part, lifting board, reducer, motor, hot air pipe, feeding chute and blast furnace. In addition, according to the specific need of the customers, it can also be equipped with gas generator, combustion room or bucket elevator, belt conveyor, quantitative feeder machine, cyclone dust collector and air inducing machine.

Working Principle of Rotary Dryer:
Wet material from the belt conveyor or bucket elevator to the hopper, and then by feeder feeding through the feeding device into the terminal. Rotary dryer cylinder into a slightly tilted to the horizontal rotating cylinder. Adding material from the higher end, low-end entry by the heat carrier, and the material into a counter-current contact, but also heat carrier and the material together and flow into the cylinder. With the rotating cylinder, the material runs by gravity to a more bottom end. Wet material in the cylinder body to move forward the process, directly or indirectly heating the heat carrier, the wet material to dry, and then the discharge end by the belt conveyor or screw conveyor sent.
