clinker ball formation of white cement

Cement Kilns: White Cement Manufacture

White clinker contains the same phase assemblage as grey clinker - alite, belite, tricalcium aluminate, tetracalcium aluminoferrite and a little free calcium oxide - but the tetracalcium aluminoferrite, which is the only dark coloured phase, is minimised. In practice, the amount of this phase in clinker is roughly proportional to the amount of iron (plus titanium, chromium, manganese, nickel ...

Clinkerization - Cement Plant Optimization

Rapid cooling of clinker can mitigate the expansion problems, however higher MgO causes ball formation in kiln, increases melt phase etc. and therefore, can disturb kiln operation. Alkalies A part of alkalies Na 2 O and K 2 O combines chemically with clinker minerals, while as the major part remains as water soluble and affects adversely cement strength (28 Day Strength).

In practice, because the majority of white cement goes into factory-made pre-cast concrete applications, a high-performance, high early strength cement is needed to maximise factory productivity. The composition of white clinkers varies widely, but a typical composition for a high performance clinker might be 76% alite, 15% belite, 7% tricalcium aluminate, no tetracalcium aluminoferrite, and 2 ...

Cement clinker - Wikipedia

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.

Clinker Cooler - Cement Cooler AGICO Cooler In

Clinker leaves the cement kiln usually at more than 1200℃ and it carries the heat content about 1250-1650 kJ/kg. So it needs to be cooled in order to: improve the cement quality and the grindability of clinker. When the clinker is rapidly cooled, the formation of mineral crystals in it is inhibited. Even if some of them have crystallized ...

Portland cement clinker - Understanding Cement

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.
