Dust collected from the hot exhaustgasesemanating from therotary kilnis known as cementkilndust and presently it is considered as a solidwastematerial to be disposed of without polluting the environment. The composition of this dust is similar to that of cementkilnraw feed and often contains high concentration of alkalies.

James G. Speight PhD, DSc, in Gasification of Unconventional Feedstocks, 2014. 2.6 Other Types. Therotary kilngasifier is used in several applications, varying from industrialwasteto 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.

Aug 18, 2019· Mostrotary kilnincinerators were of the co-current design, which provides for more rapid ignition of thewastefeed and greatergasresidence time for combustion than does the counter-current design. Hazardous or nonhazardous wastes are fed directly into therotary kiln, either continuously or semi-continuously.

The conventionalrotary lime kilnhas a length-to-diameter (L/D) ratio in the 30–40 range with lengths of 75–500 ft (22.7–152.5 m) and diameter of 4–11 ft (1.2–3.3 m). Limekilnsare usually inclined at about 3°–5° slope with material charged at the elevated end and discharging at the lower end.

Homogenization takes places when air entering the bottom of thekilnpasses through the raw mix fed from above. Raw mix is heated up to 800C bykiln waste gasesin a multi-stage cyclone pre-heater before it enters thekiln. The pre-calciner in lower part of the pre-heater almost entirely calcinates the raw mix.

Thekilnconnects with a material exit hood at the lower end and to ducts forwaste gases. This requiresgas-tight seals at either end of thekiln. The exhaustgasmay go towaste, or may enter a preheater which further exchanges heat with the entering feed.

During combustion of alternative fuels in the material inlet end of cementrotary kilns, local reducing conditions may occur and cause reductive decomposition of sulfates from calcined cement raw ...

Cement - Cement -Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
