The Bailing three-cylinder dryer has a compact structure and reasonable layout, and improves the heat exchange rate between materials and heat. The material entering the dryer is preferably a non-stick wall and a lifting plate. The temperature of the gas entering the heat exchange in the dryer should not be higher than 750 °C. If there is special requirement for high temperature drying, the inner tube inlet of the dryer and the lifting plate can be made of heat-resistant steel.
