The fineness of cement is a major factor influencing its rate of hydration since the reactions involved occur at its interface with water. Ordinary Portland cement (Types I and II) has a surface area between 3000 and 3500 cm 2 /g, while the surface area for rapid hardening Portland cement (Type III) ranges from 4000 to 4500 cm 2 /g.
2014-1-1 · The quality of the cement produced is measured through blaine which is the fineness of cement. Fineness is crucial in maintaining hydration and strength of cement. It is measured in the laboratory using an air permeability apparatus by collecting representative samples from the final product (cement) every hour or bihourly.
In principle, one should say that there is no general mathematical rule relating fineness and tph, for cement just as for raw meal. The reason is simply because this relation would be determined at least by two elements: the characteristics of the mill and the characteristics of the separator, if a closed circuit is assumed.
2020-5-1 · Nowadays, ball mills are used widely in cement plants to grind clinker and gypsum to produce cement. In this work, the energy and exergy analyses of a cement ball mill (CBM) were performed and some measurements were carried out in an existing CBM in a cement plant to improve the efficiency of the grinding process.
This mill is typically used for sample preparation to XRF analysis and delivers grind sizes down to 100 μm and smaller in as little as 30 to 40 seconds. The grinding results of the RS 200 are highly reproducible. The pulverised sample can now be analyzed by XRF or elemental analysis.
2019-7-20 · property of cement strength so as to meet the standard stipulated in ES EN 197-1. Le-chatlier apparatus: To test and control the physical property of cement soundness which is potential danger of concrete expansion and crack. Blain apparatus: to test and control the physical properties of cement fineness during finish milling.
Cement fineness is an important quality parameter in the cement grinding process. However, very few studies have been done for soft sensing of cement fineness in the grinding process.
The algorithm is tested on real problems from the cement industry, i.e., how the input's time delays affect the quality of the soft sensor estimation
2021-12-18 · Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength. Increasing fineness causes an increased rate of hydration, high strength, and high heat generation. Bleeding can be reduced by increasing fineness. However, increased fineness can also lead to the requirement of more water for workability

With our cement industry and application knowledge, Malvern Panalytical instruments enable: Control of mill operation through analysis of composition and fineness of raw mill feed. Check of mill operation through quality control of raw meal. Check of composition and material balances (e.g. K, Na, S, Cl) through filter/ESP dust analysis.
2013-3-13 · A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
Elemental Analysis of Cement. Eltra. Applications. Knowledge Base. To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps.
