3D model of a FEECO direct-fired kiln. Direct-fired rotary kilns are most often the equipment of choice in thermal processing, because they are more efficient than their indirect counterparts. There can be disadvantages to a direct-fired kiln, however.

 — Rotary kilns are very robust and versatile reactors and can be used on solar towers to perform high-temperature endothermic thermal decomposition reactions of solid materials with the aid of ...

A rotary kiln is comprised of a rotating cylinder (called the drum), sized speciically to meet the temperature and retention time requirements of the material to be processed. The kiln is set at a slight angle, in order to allow gravity to assist in …

 — The rotary kiln is a slightly inclined steel cylinder that rests on supports (bearing rollers) with an interior lining; it is equipped with a rotating motor that induces a turning motion. Such a gas/solid contactor was invented in the cement industry at the beginning of the 19th century.

The first step in sizing a rotary kiln entails thermal and chemical analyses that gather information on reaction temperatures, heat transfer properties, potential unintended reactions, and more. Depending on the process and the …

 — primary aspects: a- Bearing capacity (ultimate limit state). b- Settlement (serviceability limit state). c- Structural design (ultimate and serviceability limit states). The following...

So it's not surprising that a producer requires an ideal kiln solution. FL's ROTAX-2® and 3-base kilns deliver the best in rotary kiln designs. With the ideal temperature profile and material retention time, these rotary kilns play a …

While FEECO rotary kilns are custom designed around the material to be processed, in general, there are some standard components that serve as the basic design of a rotary kiln. The diagram shown on page 8 illustrates some of the common standard components found on a basic direct-fired kiln.

The purpose of tyres (often called riding rings) and rollers is to support the kiln and allow it to rotate with minimal friction. Rotary kilns are among the largest items of permanently moving industrial machinery, the largest examples weighing in their fully-loaded form several thousand tonnes.
