Cement, How It Is Produced

Some typical materials used for iron in cement manufacturing are iron ores, blast furnace flue dusts, pyrite clinker, mill scale, and fly ash. Ball Mill In A Cement Plant The general mining methods are surface mining, while some silicates, such as sand, are commonly mined using dredges, from lakes, rivers and waterways.

Composition of cement

This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste. By mixing these compounds appropriately, manufacturers can produce different types of cement to suit several construction environments.

The Cement Manufacturing Process

Aug 20, 2015Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are
