An investigation of clinker vs. formation heating profile and rotational velocity were conducted, and the influence on the clinker phase composition and clinker agglomeration was deduced. Independent of the raw meal used, the different clinker phases were formed in three stages: 1. C

Cement Chemistry

The liquid phase plays an important role in coating formation and nodulisation. The liquid percentage at 1450 0 C can be estimated using the formula % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is …

Clinkerization

CLINKER GRINDING. Clinker, the discharge product from the kiln, is partially cooled and broken or crushed to about ¾" – 1″ as feed to finish mills. Fineness of grind is dependent upon the type of cement to be produced. Since fineness of grind falls below standard screen size accuracy, fineness of grind is determined by use of a "Wagner ...

Sep 09, 2013· Since C2S is the least brittle of the four major clinker minerals, an increase in C2S over C3S will make the clinker harder to grind. (b) If you have a raw mix that is high in alkalis which are not balanced with sulphur, under oxidising conditions the sulphur from the petcoke will combine with the alkalis and produce a lot of alkali sulphates.

blending and grinding of clinker to cement

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. ...

While it is important to know the bulk phase composition of a clinker or cement, the surface area of each phase will also affect cement performance, especially at early ages. The surface area of a constituent is influenced by the clinker texture and grinding characteristics, which may be studied by microscopy.

Cement Manufacturing Process

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

May 25, 2016· Alite (C3S): the alite crystal is the preferred clinker phase in Portland cement clinker. The formation of alite is very complex. Alite is only formed in the presence of excess CaO, that is, at CaO/SiO 2 > 1 and is thermodynamically stable above 1250°C . This mineral is found in all the samples in a distinctive crystalline form (Figure 5).

The minerals in clinker are mainly found as crystals. A smaller amount is present in the so-called glass phase. During burning, some liquid phase is formed at the high temperature in the burning zone (BZ). The liquid phase ranges from 20 to 27% in normal clinker, however, some of the liquid does not have time to form crystals during cooling.
