Cement Industry
Instant chilling process is a physical method, which modifies the properties of steel-making slag for utilization in the cement industry (Montgomery and Wang, 1991, 1992). It is done in four stages. The first is air cooling where the molten slag is placed on shallow plates to a bed thickness of approximately 100 mm and air cooled for 4 minutes.

Automation of Kiln Mill Drive in Cement Industry using PLC and SCADA
Two basic processes, the wet process and the dry process, are used for cement manufacturing. Basic chemical reactions in the clinckerization are: Evaporating all moisture, calcining the limestone to produce free calcium oxide and reacting the calcium oxide with the minor materials (sand, shale, clay and iron).

include carbon dioxide released during energy generation to power cement manufacturing plants. Worldwide it is thought that cement making is responsible for around 7% of total man-made CO 2 emissions. The UK cement industry has agreed to reduce its primary energy consumption by 25.6% per tonne of cement produced by 2010, from a 1990 baseline.

Cement manufacturing process: Step-by-step guide
Cement manufacturing process in summary. Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.
