Cement Kilns: Early rotary kilns
The kiln feed rate was controlled by a simple valve from a recirculating pipeline, and must have been unreliable. The kiln, although very small at only 18 m long and 1.5 m diameter inside the shell, by this stage had acquired most of the standard features of the rotary kiln, designed for the aggressive conditions to be expected.
