Apr 09, 2021 Cement clinker is a semi-finished product obtained by mixing limestone, clay, and iron raw materials as raw materials in an appropriate proportion, burning to partial or full melting, and cooling. In the cement industry, the main chemical components of the commonly used Portland cement clinker are calcium oxide, silicon dioxide and a small ...
Clinker process in the cement manufacturing involves cooling of the clinker i.e., the high temperatures present in the clinkers are lowered by driving continuous air. Cooling fans are used to blow cool air and bring down the temperature of the clinkers from 1500 C to 100 C. Use of cooling fans maintains the quality of the clinker.
The clinker cooler is one of the most critical applications in cement production as the rate of cooling can be critical to the clinker quality and overall performance of cement.: Our expertise in the field
Cement clinker is discharged from the kiln into the clinker cooler. The clinker is moved from the cooler inlet to the discharge by the reciprocating motion of perforated grates. In the cooler, air is blown through the bed of hot clinker, cooling it back to near-ambient temperatures.

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 C - 1500 C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
The invention is related to a method and an apparatus for producing cement clinker, in which the cement clinker is first of all burnt in a burning zone and then cooled in a cooling zone, wherein the cooling takes place at least partially by the delivery of fuel and steam, characterised in that in a first cooling phase the delivered fuel is mixed with the cement clinker and initially pyrolysed ...

The material formed in the rotary kiln is described as 'cement clinker', 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 additive is normally ground up with the clinker.
During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter. Pure cement is formed when the cement clinker is ground into a fine powder. To regulate how cement mortar or concrete will set, gypsum is added to this powder.
The substance called clinker is dark gray as the color that appears after firing while cement is produced and it is called the material that resembles the image of marble. Its production occurs as a result of heating and combining the material called limestone and clay at approximately 1500 degrees in the furnace until it becomes liquid.
Clinker is a nodular material produced in the kilning stage during the production of cement and 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. ...
Clinker Cement; 1: Clinker is a nodular material which is used as the binder in cement products. Cement is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles etc. 2: Clinker is a granular substance containing spherical pellets of diameter 3-25 mm.

Jun 18, 2020 Clinker is a nodular material produced in the kilning stage during the production of cement and 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.
Cooling and storing The mixture inside the slightly inclined kiln is rapidly cooled from 2000 C to 100 C-200 C. Thus, the final product, clinker, is produced, and then stored, ready for the production of cement.
Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass.
Key applications on a cement plant include water atomization sprays for gas temperature conditioning in the downcomer, conditioning tower, finish mills, clinker cooler …
Types of Clinker. This includes 76% alite, 5% belite, 2% aluminum tricalcium, 16% aluminoferrite tetra calcium, and 1% calcium oxide safe. The output has declined in recent years because the use of granulated blast furnace slag for cement manufacturing makes it easy to acquire sulfate resistance. Sulfate Resistant Clinker.
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. To save energy, modern cement plants preheat the mix of raw materials before they enter the ...

A next generation clinker cooling system redesigned for better efficiency and reliability. Claudius Peters’ ETA system is a fully modular clinker cooling system designed to replace the older satellite style coolers and alleviate many of the problems associated with them.
Clinker cooling is necessary because. 1. Hot clinker is difficult to convey. 2. Hot clinker has a negative effect on the grinding process. 3. Reclaimed heat content of the hot clinker is an important factor in lowering the production cost. 4. Proper cooling improves the quality of cement.
In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.
Cement kiln dust is a by-product of cement clinker production, and has about 35 wt% of CaO and 2 wt% of MgO. Therefore, cement kiln dust has a high CO 2 storage capacity between 191 and 256 kg CO 2 /tonne of cement kiln dust. 11 Another source of Ca-based industrial waste is the paper industry.
The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be 15% lower than that of other cement ...
