Rotary kiln Wikipedia

A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.Materials produced using rotary kilns include: Cement; Lime; Refractories; Metakaolin; Titanium dioxide; Alumina; Vermiculite; Iron ore pellets; They are also used for roasting a wide variety of sulfide ores prior to metal extraction.

Rotary Kilns FEECO International Inc.

Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum.

James G. Speight PhD, DSc, in Gasification of Unconventional Feedstocks, 2014. 2.6 Other Types. The rotary kiln gasifier is used in several applications, varying from industrial waste to cement production and the reactor accomplishes two objectives simultaneously: (1) moving solids into and out of a high temperature reaction zone and (2) assuring thorough mixing of the solids during reaction.

Performance of High-temperature Slagging Rotary Kiln

Rotary Kiln The rotary kiln is 13.0 feet in diameter inside the shell and 36.8 feet in length, and rotates in the range of 0.07-0.6 rpm. Nine to twelve-inch thick high-alumina brick refractory lin-ing protects the shell. The kiln is designed to operate with a maximum flue

Rotating Kiln an overview ScienceDirect Topics

The TOSCO (The Oil Shale Corporation) process used a rotating kiln that was reminiscent of a cement kiln in which heat was transferred to the shale by ceramic balls heated in an exterior burner (Figure 4.6) (Whitcombe and Vawter, 1976).The process, which was initiated in the 1960s and 1970s and developed by the Oil Shale Corporation, is more correctly described as a retorting/upgrading process

Rotary kilns for cement plants FLSmidth

3-base kilns. The 3-base kiln is a high-quality, tradi-tional rotary kiln system. It is character-ised by a higher length to diameter ratio compared to the ROTAX-2 kiln. It has a balanced design that ensures optimal combination of stiffness and flexibility to minimise kiln crank and misalignment. The ROTAX-2 kiln uses tangential sus-

Rotary Kilns Williamson IR

Rotary Kilns. Industrial Rotary Kilns are primarily used in cement, lime, and iron ore processing. These furnaces use direct flame-fired heating methods to remove volatile compounds, instigate chemical reactions, and fuse powder into pellets. The material is rotated as it moves through the kiln, in order to evenly heat said material without
