Clinker is obtained as redhot molten texture from the lower end of the kiln during cement manufacturing. It is the intermediate product obtained, which is then processed further to make cement and the primary use of clinker is to manufacture cement. The application of clinker is as follows: Binder
Portland Cement Manufacturing Industry NESHAP Requirements1 Existing Kiln and New Clinker Cooler at Area Source of HAP Emissions Global Requirements for Portland Cement Manufacturing Plants Subject to 40 CFR part 63 subpart LLL Applicability/Affected Sources: (a) § What parts of my plant does this subpart cover?
Cement kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. The Lime Kiln is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite. The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln.

Addition of clinker dust to kiln . Hi; In some cement plants slag is used in cement kiln. What I know is that slag has C 2 S so it is used in clinker production to improve clinker C 3 S and help to catalyze clinker formation reaction (Am I right!). So, if the clinker dust which produces from production process of clinker has more C 2 S why we can''t refeed it again to the kiln inlet (like slag)?
Cement grinding. The clinker from the pyroprocessing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
Oct 29, 2019· The cement manufacturing process involves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing the cement with fine of the main ingredients used to make cement include limestone, clay, shale, iron, and manufacturing techniques will use either wet or dry grinding, but ...
Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, eggcup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor ...
Sep 08, 2018· The cement from silos is packed by machines in bags. Each bag of cement contains 50 kg or m 3 of cement. Now let''s know manufacturing of cement by the dry process. DRY PROCESS. When the available raw materials are quite hard, then this process is used . The cement by this process can be prepared by using the following operations:
Clinker produced by early static kilns was in the form of large pumicelike lumps. Rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 550 mm, together with a certain .
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 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C1500°C in the rotary kiln. ...

Cement Manufacturing Process History of Cement: Cement is a material which is highly compatible to the earth''s ecosystem and most adaptable to sustainable development. Cement is a fine powder which sets after a few hours when mixed with water, and then hardens into a solid, strong material. ... The hot clinker from kiln discharge is cooled ...
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
The clinker temperature in the kiln burning zone has to reach 1,500°C and then it is cooled in a cooler by air which decreases the temperature. The entire manufacturing process is continuously monitored and controlled from the central control room.
Portland cement clinker is made from materials mined from the earth and processed using energy provided by fuels. Additional materials, such as fly ash, kiln dust and slag may also be introduced into the manufacturing process. A chemical analysis of portland cement clinker may reveal trace
Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marblesized pellets of clinker. Read: Clinker Manufacturing Process. Cement is produced by grinding clinker (added with different active ingredients to achieve the desired properties of cement) into a fine powder. 4
silicon, aluminum and iron oxides required for the manufacturing of Portland cement. Gypsum and Pozzolana are going to be used for final cement grinding together with clinker produced from kiln. In this unit there are three crushers few meters away from the quarry; two
Cement is one of the most used building materials in the world. The process of cement production involves numerous and complex reactions that occur under different temperatures. Thus, there is great interest in the optimization of cement manufacturing. Clinker production is one of the main steps of cement production and it occurs inside the kiln.
