Raw Material Extraction/QuarryGrinding, Proportioning and BlendingPre-Heating Raw MaterialKiln PhaseCooling and Final GrindingPacking and ShippingThe raw cement ingredientsneeded for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches. Secondary crushers or hammer mills then reduce them to even smaller size of 3 inches. After that, the ingredients are prepared for pyroprocessing.
