THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie med Gad Faculty of Applied Science Chemistry Dept. Portland Cement Portland cement is made by mixing substances containing CaCO3 with substances containing SiO2, Al2O3, Fe2O3 and heating them to a clinker which is subsequently ground to powder and mixed with 26 % gypsum Raw Materials Necessary for Portland Cement

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.

#0183;#32;Types of Cement Processes Wet Process. Dry Process 74% of cement produced. Preheater/Precalciner Process. 16. Evolution of the cement Process Wet process easiest to control chemistry amp; better for moist raw materials. Wet process high fuel requirements fuel needed to evaporate 30+% slurry water.
#0183;#32;Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.
Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly. The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference. NOTE:

The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water.
cement. The white hot substance that exits the kiln, called clinker, is air cooled with the hot air returning to the kiln to conserve energy. The kiln production line is monitored and controlled by a sophisticated control system to continuously analyze and monitor every stage of the process.
