Rotary kiln
Metso's Mining and Construction Technology

Through a series of specially designed lifters, the rotary dryer showers material through the hot gas stream. By maintaining a low gas velocity, very low particulate carryover occurs, improving product yield.

Rotary dryers are suitable for:

* Mineral processing, Manufacturing
* Chemical, Petrochemical, Pharmaceutical

Main benefits of Metso systems are:

* Simple system
* Flexability in fuels used
* Year of experience with all types of dryers
* Capable of installation anywhere in world
* True understanding of process conditions
* In house engineering for custom fit applications

Rotary dryers are slightly inclined cylindrical shells supported by 2 riding rings running on a set of rollers. The kiln has a seal at both ends to prevent leakage in or out of air and material. Rotary dryers are suitable for drying a wide range of materials because of their ability to process materials having considerable variation in size and composition. A rotary dryer uses lifters mounted in the shell to produce a cascade of particles falling through a hot gas stream. The mechanical lifting of the material allows rotary dryers to be used to dry materials ranging from fine filter cake to coarse minerals. It also helps in breaking up lumps, promoting a more uniformly dried material.
