Typically the kiln is driven at speeds of 0.5 to 2 RPM, often with variable speed arrangements. Typical transit times for the lime through the kiln are from 1.5 hours to 4 hours under normal operating conditions. This is set by the speed and by the slope of the kiln, which is between 1.5° and 3° (5/16 to 5/8 inches/foot).

Cement Kilns: Firing systems

In rotary kilns, irrespective of the fuel used, the most obvious common feature of the firing system is the firing pipe (burner pipe) which passes through the kiln hood at the kiln's hot end, arranged more or less along the kiln's centre line, and through which the fuel is projected into the kiln at high velocity. The effect is rather like a bunsen burner, producing a flame that extends some way up the kiln.
