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.

Cement Clinker Quality Control During Clinker Production ...

In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.

Clinkerization - Cement Plant Optimization

Clinker free lime (CaO f) should be as high as possible to avoid hard burning of clinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incomplete clinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.
