Print Fingertip: Portland cement and the environment

Portland cement and the environment. Portland cement is manufactured by heating limestone or chalk with clay in a rotary kiln to a high temperature (about 1450°C) to produce hard nodules of clinker that are then ground with a little gypsum in a ball mill.

C2S solid solution reactivity in high-belite cement

As alite formation requires a significantly large amount of energy compared to other clinker minerals, it is theoretically possible to achieve a remarkable reduction of energy consumption in clinker manufacturing by reducing the alite content in cement. 1 The decrease of alite in clinker generally occurs with the increase of belite. For this reason, high belite cement with small amounts of ...

Cement kiln - Wikipedia

Because the clinker is brought to its peak temperature mainly by radiant heat transfer, and a bright (i.e. high emissivity) and hot flame is essential for this, high carbon fuels such as coal which produces a luminous flame are preferred for kiln firing. In favorable circumstances, high-rank bituminous coal can produce a flame at 2050 °C.

Emissions from the Cement Industry - blogs.eilumbia.edu

May 09, 2012 · To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement. Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it.
