Saxena et al. [58] reported that a new type of clinker replacing 1 % of limestone with wollastonite can be processed at 1400 °C which requires 4 kcal/kg lower energy and emits 0.013 tonnes lower CO 2 per tonne of clinker. Yet, extensive research is necessary to formulate the raw material mixture of clinker incorporating wollastonite along with ...

More than half of CO2 emissions in the cement industry are released during the process of making clinker, the man-made rock needed to produce cement. Clinker is ground in a mill with gypsum to produce portland cement. Blending limestone in the cement allows for a reduction in the amount of clinker, which reduces the carbon …

On average, to produce one ton of cement, 3.4 GJ of thermal energy (in dry process) and 110 kWh of electrical energy are needed [4, 5]. Furthermore, manufacturing a ton of cement releases 0.73–0.99 tons of CO2 [6] which primarily depends on the clinker-to-cement ratio and other factors. Unlike many other industries, energy consumption is …

As a rule of thumb, in order to produce a tonne of clinker about 1.6 tonnes of limestone is processed, i.e., around 3.5 to 5.5 MTPA of limestone is required and assuming a minimum plant life of 30 years each modern clinkering unit would need an assured limestone deposit of more than 100 to 150 MT.
