Product features
The three-cylinder dryer has the characteristics of compact structure, high thermal efficiency, low energy consumption, and reliable operation.

Stable Performance

There is no need for the gear drive and the wheel drive. The discharging temperature is less than 60%, and the packing can be produced continuously.

Quality Assurance

The final moisture content is low, and the final moisture content of the material is below 0.5%. It is the preferred product of a dry mixed mortar and slag powder production line.

Wide range of applications

Fuel is widely used, and fuel can adapt to coal, oil, and gas. It can bake lumps, granules, and powders less than 20 mm.

Easy to operate

There is no need for large and small gear transmission, and the supporting wheel is used for transmission.

Working principle

Working principle

Materials enter the inner side of the drum through the feeding device to realize the current flow drying process, then the materials enter the middle layer of the inner wall through the other end to realize the counter current drying process. They are lifted over and over in the middle layer which advances in two steps forward and one step back way. 

The three-drum dryers absorb heat from both the inner drum and middle drum, which extends the drying time and realizes the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their weight. 

Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.
