composition of cement clinker - ME Mining Machinery

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.

Portland Cement Clinker - an overview | ScienceDirect Topics

We first discuss cement production and special nomenclature used by cement industrialists in expressing the composition of their cement products. We reveal different types of cement products, their compositions, properties, and typical uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types.

Cement - Wikipedia

Meat and bone meal (MBM) is the alternative fuel with good calorific value used in cement production. The main problem with MBM combustion in a cement kiln is the high content of P2O5, which incorporates in clinker phases, influencing phase composition of clinker and hence the quality of the cement. In cement industry, only limited amount of MBM is burned to prevent adverse effect.

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.
