    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

    Cement rotary kiln is a cylinder with a steel shell which its rotational speed is usually between 1 and 2 rpm with a slope of 3-4 . Its length depends on the process. For dry processes (which are the most typical today), the length is 90-120 m (Boateng, 2016). Figure 1. schematic of a cement rotary kiln (Atmaca and Yumrutas, 2014)
