The clinker temperature in the kiln burning zone has to reach 1,500°C and then it is cooled in a cooler by air which decreases the temperature. The entire manufacturing process is continuously monitored and controlled from the central control room.
Cement kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. The Lime Kiln is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite. The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln.
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
Addition of clinker dust to kiln . Hi; In some cement plants slag is used in cement kiln. What I know is that slag has C 2 S so it is used in clinker production to improve clinker C 3 S and help to catalyze clinker formation reaction (Am I right!). So, if the clinker dust which produces from production process of clinker has more C 2 S why we can't re-feed it again to the kiln inlet (like slag)?

Aug 15, 2017· The Cement Manufacturing Process Cement is a finely ground powder which, when mixed with water, forms a hardening paste of calcium silicate hydrates and calcium aluminate hydrates. Cement is used in mortar (to bind together bricks or stones) and concrete (bulk rock-like building material made from cement, aggregate, sand, and water).
THE CEMENT MANUFACTURING PROCESS Prof. Dr Elshafie Ahmed 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 2-6 % gypsum Raw Materials Necessary for Portland Cement .
Step 5 : Clinker Cooler. The clinker tumbles onto a grate system cooled by forced air. Once cooled the clinker is ready to be ground into the gray powder known as Portland cement. To save energy, heat recovered is recirculated back to the kiln and preheater tower.
Clinker is the raw material used to manufacturing the cement. The clinker plant comprises of feed pre crusher, feed hopper, table feeders, ball mill, packaging cement plant and material handling equipment.
