cement clinker production process

  • Cement Clinker Production - an overview | ScienceDirect Topics

    Used in the plant, limestone (55–60%), marl (35–40%), and copper slag (2.5–6%) are used as cement raw materials for the production of clinker. The clinker is then finely ground in a ball mill grinding circuit together with a small amount (typically 4%) of gypsum to produce cement in the Turkey Trabzon Cement Plant ( Alp, Deveci, & Süngün, 2008 ).

  • 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
