Coal Mill In Cement Plant, Air-swept Coal Mill
Air-swept coal mill is the main equipment of cement plant, also called coal mill in cement plant, used for grinding and drying various hardness of coal, crushing the coal briquette into pulverized coal. It is the important auxiliary equipment of pulverized coal furnace.The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the composition of raw feed a wide range of coal is used. In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing.Coal in the cement industry01/01/2013· In terms of coal utilisation in the cement manufacturing process, its use as a fuel in rotary kilns is the main area of consideration. 15.3.6.

Coal Mill an overview ScienceDirect Topics
The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.In portland cement manufacturing process, Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12%, and its moisture content should be controlled within 1.0%.Cement Clinker Quality Control During Clinker 09/08/2011· 2. Alternative fuel options for the cement industry. Coal is the primary fuel burned in cement kilns, however, the use alternative fuels in cement kilns is now common and increasing. The range of alternative fuels is extremely wide. They are usually Alternative Fuels in Cement Manufacturing

The cement mill grinds the clinker to a fine powder. A small amount of gypsum a form of calcium sulfate is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added. 4.Safety in cement plant SlideShareThe cement clinker is ground with about 5% gypsum. Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal.
