  • Best Energy Consumption International Cement Review

    Benefits of Gypsum Anhydrite and Limestone ACG Materials (eg Bensted Kantro) have claimed that while limestone cannot be used as a total replacement for gypsum it is possible to replace a portion of the gypsum with limestone without significant problems with cement performance We provide high performing Clinker Grinding Plant.The finished cement is produced by finely grinding together about 95 cement clinker and 5 gypsum anhydrite the latter helps to retard the setting time of the cement This factsheet considers the principal raw materials used in cement manufacture notably limestone (calcium carbonate CaCO3) including chalk and also mudstone (clay shale).
