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 are used for the pyroprocessing stage of manufacture of portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with …
