Machine learning applications and process intelligence for cement
cement industry. 1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (e.g., pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.

1.16: Methods for Separating Mixtures
Evaporation. Evaporation is a technique used to separate out homogeneous mixtures that contain one or more dissolved salts. The method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains. Prior to using this method, the mixture should only contain …
Cement Production
In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
CO2 storage in cement and concrete by mineral carbonation
The production of cement is responsible for about 8% of man-made CO 2 emissions. CO 2 fixation by mineral carbonation in Ca- and Mg-rich raw materials such as cement-based concrete in various stages of its lifetime and magnesium silicate-based rocks (e.g. olivine) can provide a significant and long-lasting sink of CO 2.Carbonated material …

Chapter 10: Applications of CCS in the Cement Industry
Cement manufacture is responsible for around 7% of global anthropogenic CO 2 emissions. The process is unique in that around two-thirds of the direct CO 2 emissions are unavoidable as they come from the process chemistry rather than from fuel combustion. This makes reducing them particularly difficult, and carbon capture and …
