direct fired rotary kiln working principle
Rotary Dryer dryer machine rotary equipment energy. Rotary dryers consist of a horizontally inclined rotating cylinder. Material is fed at one end and discharged at the other end. In direct-type rotary dryers, hot gases move through the cylinder in direct contact with the material, either with or against the direction of its flow.

A rotary kiln is classified as a direct-fired or indirect-fired kiln depending on the heating method and can be selected considering which process is more suitable. The direct-fired has the advantage of high heat efficiency, but the generation of exhaust gas is large, and subsequent treatment is required more.

How Rotary Kilns Work. Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction. These treatments can be applied to powders, granulates, suspensions and green bodies. A rotary kiln consists of a cylindrical

An improved heat transfer model has been developed for a direct-fired rotary kiln. The treatment of radiant heat transfer was based on the Reflection Method developed by Succec and applied by Gorog, and was extended to account for radiation from a flame. Some elements of the Resistive Network Method and Zone Method were incorporated in the model.
