Aug 20, 2015 Cement 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 recombined into new compounds.

Cement Milling

Cement Milling

Cement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media steel balls. Grinding clinker requires a lot of energy. How easy a particular clinker is to grind grindability is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
