Grinding of clinker consumes power in the range of kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.

The remaining elements unite to form a new substance called clinker. Clinker comes out of the kiln as grey balls, about the size of marbles. Clinker is discharged redhot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. The heated air from the coolers is returned to the kilns, a ...

A Viking longship, displaying the overlapping planks that characterize clinker construction. Clinker built (also known as lapstrake) is a method of boat building in which the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank.. The technique originated in Scandinavia, and was successfully ...

Furthermore, underburnt clinker leaves an uncompleted combination of the different elements present in the raw meal, while overburnt clinker generates higher SO x emissions, due to a decomposition of the ye'elimite phase (C 4 A 3 ). Too high a temperature in the clinkering zone also leads to a risk of ring formation or melting that can force ...

Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The cement grinding station does not produce clinker and processes cement through purchased clinker. Unlike cement clinker production lines that rely on raw materials in mining areas, independent production clinker grinding units are mainly located around major cement sales markets, that is, near large and mediumsized cities.

Clinker can be substituted with other cementlike materials, including waste from coal combustion and steelmaking. This can affect the cement's properties, however, so is only suitable for some end uses.
