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.

The use of alternative fuels and raw materials (AFR) for cement clinker production is certainly of high importance for the cement manufacturer but also for society as a whole. Alternative fuel utilization began in the mid 1980s. Starting in calciner lines, up to almost alternative fuel firing at the precalciner stage was very quickly achieved. Alternative fuels are mainly used tires ...

Manufacturing process | Home : Lafarge - Cement

The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
