The cement rotating dryer mainly consists of rotary body, lifting blade, transmission device, supporting device, seals and other components. The cement rotating dryer adopts the new type dryer lifting plate device, which has the functions of guiding, flowing, lifting, and so on. It is able to make the material evenly distribute on the radial cross section of the drying machine and make the feed screen in the state of thin, uniform and full, so the material can contact with the hot gas stream completely for achieving the purpose of fully utilizing the thermal energy. Generally speaking, the coal consumption and electric consumption can be reduced more than 10% to 15%, the output of each dryer can be improved more than 10% to 15% per hour, so this drying machine has been widely used in the cement and mineral processing enterprises.

The cement rotating dryer is mainly used for drying material with a certain degree of moisture and granularity in concentrating, construction, and metallurgy and chemical plant. With the strong adaptability, broad applications and simple operation, this drying machine is widely used.

This dryer uses the heating method of concurrent, so when it works, the material will be fed into the barrel from the flow box, that is, the material will be pull back by the spiral lifting plate. Due to the inclined placed of the drying machine, on the one hand, under the forces of gravity and rotary, the material will flow back; on the other hand, the material will be repeated kicked up by the lifting board, raising to the top and then continuing to lift and down, so that the material in the barrel will form a uniform curtain and do the heat exchange with the hot gas stream in the barrel completely.
