Description of Rotary Drum Dryer

The Rotary Drum Dryer is also called rotary dryer, rotary tube dryer, rotary cylinder dryer,  widely used in the field of building materials, metallurgies, chemical industry, cement plant and so on. It can dry slag, coal, mining powder, clay, sand, limestone and so on. It is composed of rotary drum, lifters, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.

According to the basic structures of the Rotary Drum, it can be divided into three types: single drum dryer, double drum dryer and triple drum dryer. In our factory, single drum dryers and triple drum dryers are produced on daily basis.

Co-current flow is used for heat sensitive materials even for high inlet gas temperature due to the rapid cooling of the gas during initial evaporation of surface moisture, whereas for other materials countercurrent flow is desirable in order to take advantage of the higher thermal efficiency that can be achieved in this way.

To ensure that the dryer is loaded close to optimal, it is important to know the amount of solids that can be held up in the flights. If they are underfilled, the dryer will be performing inefficiently, below its capacity. Excessive overload of the shell will result in a

proportion of the material transported by kiln action,and the contact with the hot gases is limited. The residence time of the solids will be reduced and the quality of the product may be unacceptable.
