RAW MATERIALS IN CEMENT PRODUCTION
Chalk is soft raw material, it does not require crushing. Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness of limestone The more clay substances, the lower its hardness. This is an excellent raw material for cement production.
