Cementkilnsare used for the pyroprocessing stage of manufacture of Portland and other types of hydrauliccement,inwhich calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes ofcementare made per year, andcementkilnsare the heart of this productionprocess: their capacity usually defines the capacity of thecementplant.

Shaftkiln, also known asverticalkilnorverticalshaftkiln, it isverticaland fixed.Shaftkilnis a necessary type ofcementkilninthecementproduction. As we all know, VSKcementplant is widely applied in thecementindustry.

CementManufacturingProcessPhase IV:KilnPhase.Kilnis a huge rotating furnace also called as the heart ofcementmakingprocess. Here, raw 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.

were proposed to mitigate various negative phenomena experienced in the operations ofverticalkilns. Keywords :Verticalshaftkiln, Operation, strategy, investment, Burner, Firing, Profile. 1.0 Introduction Theverticalshaftlimekilnshave been shown to posses a lot of potentials in the lime industry ( Okonkwo etal 1991).

WetProcessand DryProcessWetProcess. The wetprocessofcementmanufacturingrefers to grinding raw material into slurry after mixing with water and then feeding them into the wetprocesskilnfor drying and calcination and finally forming clinker.

Acementkilnincinerator is an option that can be used to incinerate most hazardous and non-hazardous wastes. The rotarykilntype is the typical furnace used in allcementfactories. Rotarykilnsused in thecementindustry are much larger in diameter and longer in length than the previously discussed incinerator.

CLINKER FROM ROTARY ORVERTICALSHAFTKILN. Dear Sirs, what is the difference between a clinker produced in a rotarykilnand the clinker produced in averticalshaftkiln? I know that the disadvantages of the VSKkilnare the inclusion of ash in the clinker, the problem with homogeneity of heat distribution, the low production.

TheKilnFeed is transported to the Noduliser with the help of an air-lift. At this stage, water is sprayed on the feed (appx. 10%) to make nodules, which are then fed into theVerticalShaftKilns(VSK) through feed chute for burning and fusion. The temperature goes up to 1400°C in the burning zone. The nodules travel very slowly in thekilns.

Modern daycementis an unusual industrial product produced in huge quantities in special plants that can produce nothing else. It is produced by a combination of unusual unit operations involving mining, very fine scale blending of raw materials, very high temperature clinkering reactions, controlled cooling, grinding, blending, and finally shipping under controlled conditions.
