Rotary Kiln an overview ScienceDirect Topics
The main components of a rotary kiln are an inclined cylindrical, refractorylined reaction shaft equipped to rotate over rollers and a burner Process heat is generated by burning fine coke or coal contained in the charge and by the exothermic heat of the PbO reduction by CO This process produces molten lead and a slag with 3–5% PbRotary 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 drumRotary Kilns FEECOHistorically, the construction of rotary kiln shells has closely paralleled the construction of boilers The engineers who pioneered the first rotary kilns all had a background in locomotive construction Shell sections were made from flat rolled plate, of thickness typically in the range 1825 mmCement Kilns: Design features of rotary kilns
