Manufacture Of Cement

The clinker is cooled rapidly to preserve the metastable compounds and their solid solutions -dispersion of one solid in another -which are made as the clinker is heated. Clinker is then cooled and ground in tube mills (Fig. 24), where 2-3% of gypsum is added. Generally, cement is stored in bags of 50 kg.

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. There are two main forms of cement: Geopolymer cement and Portland Cement.Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.

What are Cement Clinkers? (with pictures)

Jul 19, 2019 · Cement clinkers are formed by the heat processing of cement elements in a kiln. Limestone, clay, bauxite, and iron ore sand in specific proportions are heated in a rotating kiln at 2,770° Fahrenheit (1,400° Celsius) until they begin to form cinder lumps, which are also known as cement clinkers. These are usually ground with gypsum to produce the fine powder later mixed with liquid to .
