In the cement clinker burning process, the soft sensing of free calcium oxide (f-CaO) content has been a challenging task due to the dynamic time delay between f-CaO content and process variables, the different time scale between process variables and f-CaO content, and the strong nonlinearity of the process data. With the development of …
Better and cheaper cement: Optimising the right clinker …
Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

Clinker creates cement if combined to gypsum to monitor the cement settling properties and to maintain compressive strength or finely ground.
Hoffmann Green Cements: first decarbonated cements 0% clinker
The manufacture of conventional cement is very polluting. In particular, it requires a lot of energy to produce clinker, the main component of cement. To reduce its carbon footprint by 80% by 2050, the cement industry must therefore innovate.. Hoffmann Green is fully committed to this mission. Decarbonated cement 0% clinker is already an accessible …

Hydration and hydration products of two-phase Portland cement clinker …
Alkalis are important minor constituents of ordinary Portland cement clinker. Na2O, in particular, is incorporated into the aluminate phase and alters its crystal structure. For this study, well defined Portland cement clinkers consisting of alite and aluminate doped with different amounts of Na2O were used. Isothermal conduction calorimetry of …
NOx Concentration Prediction With a Flexible Cascaded Echo …
Measuring nitrogen oxide (NOx) concentration accurately and timely is critical for pollution control during cement clinker calcination. However, due to the harsh environment and complex reactions, NOx concentration in calcination systems cannot be directly measured. In this article, a flexible cascaded echo-state network (FCESN) is developed for online …
Understanding the Role of Clinker Grinding in Cement …
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.

Portland cement clinker
Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail …
The Soft-Measuring Research on New Dry Process Cement Clinker …
The free calcium oxide (f-CaO) contents directly reflects the quality of cement clinker. The content of free calcium oxide can't be measured directly on-line at the practical production and the chemical analysis is complicated and time consuming. A number of samples has been collected from the cement DCS control system, through data processing and …

Clinker factor determines the CO2 footprint of cement
In OPC, clinker factor is ~90 per cent thus, it has a carbon footprint of around 800 – 850 kg/MT of cement. When clinker is replaced with SCMs, the CO2 emissions are reduced as SCMs don't have embodied carbon emissions. That is why blended cement have much lower carbon footprint than OPC. Currently in Portland Slag …
The clinker manufacturing process
