Cement clinker Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 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.

Energy Consumption Benchmark Guide: Cement Clinker

The energy use among the 15 plants depicted in Figure 4 varies from a low of 3.68 to a high of 6.87 gigajoules per tonne of clinker. The average energy use for the 15 plants is 4.69 GJ/t. But the average for the four most energy-efficient plants (upper quartile) is only 4 GJ/t. In other words, there is a 15-percent difference between the

Cement kiln Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
