Cement kiln - Wikipedia

Clinker produced by early static kilns was in the form of large pumice-like 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 5-50 mm, together with a certain amount of dust abraded from the nodule surfaces.. Clinker minerals react with water to produce the hydrates that are ...
