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...
