The new dry cement production line is usually divided into three stages raw material preparation, clinker firing and cooling, and cement preparation and delivery. Each stage is important for cement production, especially the firing and cooling of clinker.
Grate cooler is one important main equipment in cement plants burning system, being responsible to clinkers temperature cooling, delivery, crushing and system heat recovery.
Cooling clinker. The clinker temperature is an important indicator of the grate cooler performance, which reflects the cooling efficiency of the grate cooler, and also creates conditions for the conveyer, storage, and cement grinding of clinker in subsequent processes.
Cement manufacturing is an energy intensive activity and the choice and mix of primary and alternative fuels affects both the environmental impact and economics of the process. Total energy cost can represent 65-75 of the variable costs in the process.

Clinker Grate Cooler. n a cement plant, grate cooler is a basic machine in the calcining cement system, its main function is to make the ripe cement material to next system.
Hot clinker discharge from the kiln drops onto the grate cooler for cooling from approximately 1350-1450 C to approximately 120 C.
The relative proportions and different solubilities of these various types of calcium sulfate, and of the different forms of clinker sulfate, are of importance in controlling the rate of C 3 A hydration and consequently of cement set retardation.

cement production line,cement making plant,cement. the cement making process is mainly composed by crushing and crushing and prehomogenization, preparation of raw materials, preheating and precalcinating, calcinating of cement clinker and packaging of cement powders.
The kiln is a large furnace that is fueled by coal, oil, gas, coke andor various waste materials. The product called clinker from the kiln is cooled, ground, and then mixed with a small amount of gypsum to produce portland cement.
1510176C 2750176F Cement clinker is formed The kiln is angled by 3 degrees to the horizontal to allow the material to pass through it, over a period of 20 to 30 minutes. By the time the raw-mix reaches the lower part of the kiln, clinker forms and comes out of the kiln in marble-sized nodules.
Key applications on a cement plant include water atomization sprays for gas temperature conditioning in the downcomer, conditioning tower, finish mills, clinker cooler.
After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. 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.
