Get PriceBlended cements are produced by inter-grinding Portland cement clinker (Clinker is the main product of Portland cement manufacture and is generated by heating raw materials (limestone, iron ore, and alumino-silicates such as clay) together at temperatures of about 1400–1500°C.) with supplementary cementitious materials (SCMs) or by blending Portland cement with SCMs such as fly ash from coal combustion in electricity-producing plants or blast…

When the liquid (molten)slagis quenched with water in a granulation plant (Fig. 5), a glassy and granular product is created, which must subsequently be ground to produce a fine powder, which is used as aclinkersubstitute. Ground granulated blast furnaceslag(GGBFS) has similar cement-like properties to Portland cement.

The only way to avoid this is togrind clinker and slagseparately. For the design of aslag grindingplant the special properties of granulated blast furnaceslaghave to be considered. Granulated blast furnaceslagis moist, abrasive, fine grained and difficult togrind. It also needs to be ground very finely.
Grindability and particle size distribution of the clinker and the slag and clinker-slag mixtures were determined together with the kinetic characteristics of grinding. The influence of fine grinding on the hydraulic activity of slag was also studied. The strengths of cements produced by both simultaneous and separate grinding were compared.
The so produced cement clinker is ground together with gypsum and/or anhydrite, thus forming the final product cement. Depending on the availability of the raw materials and market-specific requirements, further extenders are added to the common grinding process such as granulated blast-furnace slag.
When the liquid (molten) slag is quenched with water in a granulation plant (Fig. 5), a glassy and granular product is created, which must subsequently be ground to produce a fine powder, which is used as a clinker substitute. Ground granulated blast furnace slag (GGBFS) has similar cement-like properties to Portland cement.

Dec 17, 2020· Australia: Adbri subsidiary Cockburn Cement has approved a US$152m upgrade to its Kwinanagrindingplant in Western Australia. It says the investment will consolidate the cement operations at its Kwinana site. At presentclinkeris transported by truck from the Kwinana Bulk Terminal to cement mills at both the Kwinanagrindingplant and the company’s integrated plant at Munster.
Additives used in blended cements, such as pozzolan orslag, may not be available at the location of theclinkerplant. As an economic measure, many cement companies have opted to shipclinkerto satellitegrindingfacilities for the supplementation of readily available additives at the location of thegrinding…

Ordinary Portland Cement is made by grinding Clinker with a few other minerals. Other Cements such as limestone Cements, Pozzolanic Cements, Blast Furnace Slag (BFS) Cements, and masonry Cements, contain greater amounts of other minerals and have a much broader composition range. Clinker is made in a chemical process which is energy-intensive.
Cement is usually grey but also found in white, which is usually more expensive than grey cement. Chemistry of Cement. Cement is an organic material obtained by mixingtogethermaterials such as limestone, sand, clays and iron ores; burning them at aclinkertemperature andgrindingthe resultingclinker.
It is a hydraulic cement having sulphuric anhydride (SO3) content less than 5% and made by intergrindingmixture of at least 7% granulated blast furnaceslag, calcium sulfate and a little amount of lime or Portlandclinker.
