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.

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

Jul 06, 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.
