Following is the procedure of manufacturing cement by dry process using modern technology: Boulders of limestone upto 1.2m size are transported in huge dumpers upto 300kN capacity and dumped into the hopper of the crusher. The hammer mill crushers of single stage are now used for crushing. The crushed limestone now of 75mm size is moved from

Cement Manufacturing Process. The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers.

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

Wet process; Dry process; Wet process- The wet process was popular for the manufacturing of cement because of the possibility of more accurate control in mixing of the raw materials. In the wet process, the slurry contains 35% to 50% water. That is why, to dry the slurry more fuel is required.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
