  • Ordinary Portland Cement Production | AGICO Cement Plant

    Portland cement derives its name from Portland, England, in many cases, also called silicate cement It is a kind of hydraulic cementing material made of calcium silicate cement clinker, limestone or blast furnace slag (less than 5%), and an appropriate amount of gypsum At present, Portland cement has been widely used in residential construction, traffic construction, largePortland pozzolana cement, portland slag cement, and portland fly ash cement are all made by adding active admixture and an appropriate amount of gypsum based on Portland cement clinker They are similar in nature and scope of application, so they can be used interchangeably in most cases However, the physical properties and characteristics of the active admixture arePPC Cement Manufacturing Process Portland Pozzolana Cement13/04/2020· The entire manufacture of portland cement process in a modern plant is now control through a microprocessor base programmable logic control system to maintain a consistently uniform quality of cement and a high rate of production The entire operation of the plant is control centrally in a single control room and the plant employs minimum of manpowerManufacture of Portland Cement Process and Material use
