With the rotation of the rotary kiln and due to the gradient distribution of the temperature of the lining, part of the molten ash may solidify on the lining material to form a new kiln skin. As the kiln rotates, part of the ash and slag may be melted again and reach a certain balance, so that the kiln skin will not thicken.

With rotary kilns, long un-interrupted run-times are necessary to minimise damage to (and replacement cost of) the kiln lining, and in general to minimise operating cost. But, in addition, rotary kilns involved vastly greater capital expenditure, and high utilisation was required to pay this off at an acceptable rate.

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 …
