Cement Kilns: Clinker Minerals

Early clinker composition. The phase diagram for the CaO-SiO 2 (C-S) system (shown right) was first accurately determined by Day, Shepherd and Wright in 1906.This shows that there are four stoichiometrically distinct calcium silicates (each with multiple polymorphs): CS, C 3 S 2, C 2 S and C 3 S.Portland cements contain mixtures of C 2 S and C 3 S.The zone containing Portland cements is

Kiln phase. Since clinker is a complex mixture of ingredients, it requires a multi-staged heat treatment, which is done in the kiln. The main part of the manufacturing process of clinker takes place in the kiln. The stages in the kiln phase are as follows: Evaporation of free water: A pressure above atmospheric is required to vaporize the water from the slurry mixture of raw materials. Water ...

EFFECT OF FERRITE PHASE ON THE FORMATION AND

duction of clinker. The liquid phase are mainly composed of CaO, Al 2 O 3 and Fe 2 O 3 in burning process. The vis-cosity of liquid phase varies with the ionic state in the liquid composition. CaO is always dissociated into Ca2+ ions, while Al 2 O 3 and Fe 2 O 3 owing to amphoteric oxide, can be dissociated into MeO 4 5-or Me3+ ions in the melting state [17]. As shown in the following ...

LIQUID PHASE - Page 1 of 3

Re: LIQUID PHASE. Hi Stephen, In addition to the good information that Vinayak has provided, excessively high liquid phase may also promote attack of the bricks, "washing out" of coating, hard to grind clinker and increased tendency to form "snowmen" in the cooler.. Excessively low liquid phase promotes little or no coating, very hard to burn clinker (high free lime), increase in clinker ...

Review: liquid phase sintering SpringerLink

01/01/2009  Liquid phase sintering (LPS) is a process for forming high performance, multiple-phase components from powders. It involves sintering under conditions where solid grains coexist with a wetting liquid. Many variants of LPS are applied to a wide range of engineering materials. Example applications for this technology are found in automobile engine connecting rods and high-speed metal cutting ...

Effect of clinker composition on grindability -

01/03/1979  The liquid phase appears to play an important part in the clinker grindability; a higher liquid phase in the clinker shows a higher work index. The increase of liquid can be attributed to the increasing iron and alumina contents (fluxes) ; on rapid cooling the liquid present fails to crystallize and forms a glass instead, thus increasing the strength of the clinker. The hydraulic modulus (H.M ...

RAW MATERIALS Burning the mix - News, Events Training

Understanding the process of clinker manufacture – how raw materials are trans-formed into clinker – is the key. This transformation involves both chemical and physical processes. The microstructure of clinker is a function of kiln feed properties and the pyroprocessing conditions. Knowing what happens where, why, and how, can lead to optimising pro-duction, costs, and quality. In turn ...

Cement hydration - Understanding Cement

The Understanding Cement book/ebook contains a more detailed description of the hydration process and the hydration products. Clinker is anhydrous (without water) having come from a hot kiln. Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage. The reaction with water is termed "hydration". This involves many different ...

role of iron and alumina in liquid phase? - Page 1 of 2

06/07/2013  A sudden influx of iron oxide in a typical clinker will make the liquid form earlier in the kiln and will probably make the coating strip away. Iron oxide is the easiest to use to control the ratio because it is relatively pure and can be added or removed in very small quantities to have an effect. If there is a pure source of alumina this could be used, but these are expensive unless a ...
