Discuss chemical reaction which take place in the rotary kiln that lead to the manufacture of clinker and then sketch when neces

Material residence time in the rotary kiln of a precalciner process is typically 30 minutes. The clinker exits the rotary kiln at ~ 1200 C and is cooled to ~ 60 C in the cooler before going to storage and then being ground with gypsum (calcium sulfate) to produce cement. The air which cools the clinker is used as preheated combustion air thus improving the thermal efficiency of the process

    Dec 26, 2019 Dec 26, 2019 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. They are normally used to carry out processes such as (i) calcination, (ii) thermal desorption, (iii) organic combustion, (iv) sintering/induration, (v) heat setting, and (vi) many more processes

    The upright furnace uses a ratio of 70% hot metal to 30% scrap. Rotary furnaces can use more scrap but require longer heat time. External application of heat is not required. The hot metal and the exothermic reaction (heat release) from the oxygen and the carbon and silicon provide the necessary heat
