Cement Manufacturing Process

Cement Manufacturing Process

+

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed 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.

Rate data were collected for calcinations during cement production for 4 years at the same time intervals. The amount of CaCO3 consumed in tons was plotted against time in minutes. The plots gave good numerical fit (R2>) for all the model equations studied but the parameter estimates for K, CAO and n varied widely (>5%) for all rate equations except the rate equation for zero order...
