Cement Kilns: Clinker

Clinker produced by early static kilns was in the form of large pumicelike lumps. Rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 550 mm, together with a certain amount of dust abraded from the nodule surfaces.. Clinker minerals react with water to produce the hydrates that are

Cement is the binder that holds together urban centers around the world. To make it, limestone, sand, and other additives are combined in rotating kilns at temperatures of up to 1450°C. This process yields a granular intermediate known as clinker, which is then ground in mills to produce cement powder.
