CEMENT RAW MATERIALS International Cement Review

The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.

RAW MATERIALS IN CEMENT PRODUCTION

Feb 07, 2019 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.
