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 ...

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Power requirement is very high. Speed control ratio is 1:10. Very low creeping speeds of 1 rpm may be required. Starting torque should be in the range 200 to 250% of full load torque. The acceleration of the drive should be completed in about 15 s. For small periods an overload capacity of 200250% may be required.

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 ...

Introduction. The use of Sankey diagrams has long been standard practice in science and engineering. The diagrams are described as graphical heat balances (Minister of Fuel and Power 1944, 709), heat balance diagrams (Christensen 1990, 394), energy flow charts (Schnitzer 1991), or simply Sankey diagrams (Pople 2001, 138).The diagrams frequently focus on energy flow and its distribution to ...
