Having established the burnability of a kiln feed Section It is possible to determine a temperature at which the feed will produce a clinker with a given free lime by interpolation between the measured plotted points as in Fig the combinability temperature of the feeds is defined as the temperature at which the feed will reduce to 2% free lime
·The main factors affecting clinker reactivity and PSD Clinker mineralogy and nodule size depend largely on the feed composition and the amount distribution and nature of the melt phase formed in the burning zone The clinker melt promotes the reaction between belite C 2 S and free lime to form alite C 3 S so it is critical for clinker
·Estimating emissions generally involves two emission factors an emission factor for clinker production and an emission factor for Cement Kiln Dust CKD production Clinker emission factor The clinker emission factor is the product of the fraction of lime in the clinker multiplied by the ratio of the mass of CO2 released per unit of lime
·80 percent of the raw material is less than 75 microns Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns The European Cement Research Academy ECRA estimates that up to 70% of the power consumed in

As clinker is the element within cement responsible for the majority of both its cost and carbon emissions reducing the clinker content also know as the clinker factor of cement has the dual benefit of lowering both the cost of its production and its environmental impact
Loss of carbon dioxide from the limestone ie calcining Clinker liquid and nodule formation Above about 1300 °C the proportion of liquid starts to increase by 1450 °C perhaps 20 30% of the mix is liquid The liquid forms from melting ferrite and aluminate phases and some belite The liquid content is more than the sum of the
When limestone is converted to clinker CO 2 is released also known as process emissions A substantial amount of heat is needed to start and sustain the chemical reaction leading to further CO 2 emissions also known as combustion emissions The clinker is finely ground and mixed with gypsum and often with alternative raw materials to
·The carbon intensity of industrial cement production could be reduced if the high temperature kilns used to decompose limestone CaCO3 s were replaced One possible solution is to use electrochemical reactors to convert CaCO3 s into Ca OH 2 s The challenge is that the continuous flow electrochemical reactors reported to date all
·Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 3 25 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C 1500°C in the
