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 …

In 1996, precalcination of the first line was made and clinker production capacity was increased to 1.350.000 tons/year and cement grinding capacity was reached 1.850.000 tons/year. Investments for the fourth cement mill with a capacity 175 t/h and a cement silo with 10.000 tons capacity were completed by 25th May 1999.
What is Cement Clinker? | Datis Export Group
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
