Cement Manufacturing – A Wet Process with Flow Diagram - Civiconcepts
The wet process of cement manufacturing too popular for several decades because of the possibility of more accurate control while material mixing. After that, the dry process of material mixing gained momentum with the modem development of the technique of dry mixing of powdered materials using compressed air.CHAPTER 3.0 CEMENT MANUFACTURING PROCESSChapter-3 Cement Manufacturing Process 37 the negative air is vented out to the atmosphere. The collected fine powder is retrieved with the help of rapping mechanism and the same is fed to the process. 3.1.4 Blending and Storage After filling the powdered materials from mill to a certain level in theCement Production - an overview ScienceDirect TopicsThe production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions IFC, 2017 . Cement-based structures constitute the largest surface area of all man-made structures Odigure, 2009 .

Kiln is a huge rotating furnace also called as the heart of cement making process. Here, material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material like limestone releases the carbon dioxide.The cement kilnWet process kilns. The original rotary cement kilns were called & 39;wet process& 39; kilns. In their basic form they were relatively simple compared with modern developments. The meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
