2021-5-1  Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.

2019-12-4  The direct CO2 intensity of cement production increased 0.5% per year during 2014-18. To get on track with the SDS, a 0.8% annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS).

Energy Use Cement Cement Cement Industry

Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills.
