CEMENT RAW MATERIALS International Cement ReviewCement Wikipedia

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 kilnsGreen cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials thereby reducing consumption of natural raw materials water and energy resulting in a more sustainable construction material

Raw Material Preparation Industrial Efficiency Cement >About Cement >Cement Manufacture

The production of one ton of portland cement requires more than 15 ton of raw materials Raw material preparation is an electricity intensive stage typically requiring 25 to 35 kWh of electricity per ton of processed raw material although the energy consumption can be as low as 11 kWh/tCement is then pumped to silos for storage and dispatch Mineral additions and SCMs are added to reduce the amount of clinker in cement This in turn reduces the fuel power process emissions and raw materials associated with cement production At the same time it creates a use for material considered to be a waste product of other industri
