How Cement Is Made in Rotary Kiln | Rotary Kiln …
How Cement Is Made In A Rotary Kiln. Originally, when the process was first developed, manufacturers used the "wet kiln" process. This involved pouring in a slurry of clay, limestone, and water. While the process was easy to set up, it required an absolutely enormous rotary kiln to be effective – at least 200 meters long. This is because ...

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 …
