Rotary kiln length

Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed incinerator. The manufacture of cement from limestone requires high kiln temperatures (1,400 C) and long residence times, creating

    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. Direct-fired kilns utilize direct contact between the material and

    Cement Kilns: Design features of rotary kilns

    The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were
