Projecting future carbon emissions from cement production …

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO2 emissions generated in cement manufacturing, due to the combustion of fuels and the decomposition ...

Deep decarbonisation of industry: The cement sector

Clinker, and clinker substitutes, are the active components that confer cement its binding properties. Producing traditional cement clinker is an extremely energy and CO 2 intensive process. In the EU, 90% of clinker is now made via the more energy efficient dry clinker-making process (2). Older, less efficient wet

Everything you need to know about clinker/cement Grinding

For instance, if the clinker is wet, the production rate will drop if the mill system cannot accept additional or replacement moisture. ... The static's generally produce cement superior to a Sturtevant, similar to a Raymond, and worse than an H.E.S. based on Rosin-Rammler. In short follows these rules of thumb: ...
