Clinker is a nodular material produced in the kilning stage during the production ofcementand is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
Get PriceThe powdery or granular mixture quickly solidifies into spherical nodules ofclinker. Cooling and storing. The mixture inside the slightly inclinedkilnis rapidly cooled from 2000°C to 100°C-200°C. Thus, the final product,clinker, is produced, and then stored, ready for theproductionofcement.
Manufacturing Clinker Manufacturing.Purbanchal Cement Ltd. (PCL) is engaged in the production of Clinkers and Cement. Thelime stoneis crushed in primary and secondary crusher and conveyed to thestorage hopper. Each raw material/consumables such ascrushed lime stone, additive and iron dust are weighed as per designed quantity and fed to raw mill for grinding.

This concept is used in producing a type ofclinkerwith up to 30% less carbon dioxide emission. Energy efficiency improves and the electricity costs for themanufacturing processare about 15% lower as well. Use ofClinker: Conversionto Cement.Clinker, combined with additives and ground into a fine powder, is used as a binder incementproducts.
Clinker productioncan be divided into preheating and pre-calcining,clinkersintering, andclinkercooling three stages. Cyclone preheater,cementkiln, andclinkercooler are three maincement manufacturingmachines in thisprocess.

The clinker manufacturing processThe preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal. The calcinations of the material begin during this stage, changing its phase to the oxide phase for each component to be ready for the burningprocess.
The wetprocessrequires 0.28 tonnes of coal and 110 kWh of power to manufacture one tonne ofcement, whereas the dryprocessrequires only 0.18 tonnes of coal and 100 kWh of power. The major operations carried out in thecement clinker processing plantare as follows:
Developing theclinkeris the next step where we use the raw materials of limestone to increase distributivity ofcement, calorific value coal as an energy source and iron ore to help liquidize the material and ease the formation ofclinker. TheClinkeris then heated in the kiln under 1400 degree Celsius.
Coal is used for heating the raw materials at 1450 degrees centigrade to turn intoclinker. The grade of coal supplied in thecement manufacturingindustry depends on the grade of limestone used inthe cement manufacturing process. If the limestone used inthe cement manufacturing processis of high grade then low-grade coal is used and vice versa.

In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in thecement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After theclinkeris fired, the temperature begins to decrease.
10.3.3Cement manufacturing.Cement manufacturinghas several opportunities for WHR, specifically in theprocessstep where theclinkermaterial is produced. Forclinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln andclinkercooler have hot exhaust streams where waste heat could be recovered.
