Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium 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.

Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.
