Clinker For Cement Production

In portland cement manufacturing process, the quality of cement clinker directly affects the quality of the finished product cement.. The following are several important factors affecting the cement clinker quality. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker.

CLINKER GRINDING IN CEMENT PRODUCTION

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

How Does Clinker Cooler Reduce Cement Production …

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 ...

CLINKER PRODUCTION Hilger

Clinker Burning - Supreme Discipline in Cement Production. If clinker is not the best, cement can never be good. Clinker quality has the biggest impact on cement quality. And the clinker burning process determines, as well as raw meal, the quality of clinker. Clinker burning process is the cement production step with the highest cost.

Clinker Production - thyssenkrupp Industries India

Clinker Production. In modern cement plants, the burning process is performed in a chain of three systems. In the multistage cyclone preheater with calciner, the raw meal is preheated to about 800 to 900 C and decarbonated by kiln exhaust gases.

Portland cement clinker

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.

Difference Between Clinker and Cement Compare the ...

Oct 23, 2011 The key difference between clinker and cement is that clinker appears as marble-like nodules, whereas cement is a very fine powder.. Earlier, people did not have sophisticated homes; therefore, they used simple things found in the environment to build houses. But today there are many advanced materials and equipment, which assist in constructions.
