Rotary kiln (large rust-colored horizontal tube at center right) at a Wyoming cement plant General layout of a direct fired countercurrent rotary kiln used in cement manufacture Rotary kiln body, with drive gear and 2 tyres (riding rings). A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.
A burner for a rotary kiln consists of a central pipe (5) for introducing an oil or gas lance, a first concentric pipe (8) for introducing primary air and a second concentric pipe (1) for introducing a mixture of solid fuel and carrier air into the burning zone of the kiln. The pipes (5, 8 and 1) form mutually annular channels, the primary air channel being located inside the solid fuel air.
Dec 26, 2019 Rotary Kiln. A rotary kiln is an inclined, rotating cylindrical reactor through which a charge moves continuously. The rotary kiln is a thermal processing furnace used for processing solid materials at extremely high temperatures in order to cause a chemical reaction or physical change.

The purpose of rotary kiln tyres and support rollers are support the rotary kiln, which allow rotate with minimal friction. Rotary kiln is among the largest items of permanently moving industrial machinery, the largest examples weighing in their fully-loaded form several thousand.
This chapter provides a basic description of rotary kiln operation. Unit operation equipment and other components are added together to form the rotary kiln system for material processing.
Dec 26, 2019 Rotary kiln can be either of the direct-fired type, or the indirect-fired type. In a direct-fired kiln, a fuel is burnt in the drum, and the material is processed through direct contact with the flue gas. In an indirect-fired kiln, material is processed in an inert environment, and is heated through contact with the shell of the kiln, which is heated from the outside to maintain.
In a direct-fired rotary kiln, the burner is situated inside the kiln body, that is, inside the reaction chamber. The material is heated directly by the burner.
