  • Portland cement clinker Understanding Cement

    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.

    A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m

  • What is Cement Clinker? Composition, Types & Uses Civil

    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.

    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.

    CLINKER GRINDING. Clinker, the discharge product from the kiln, is partially cooled and broken or crushed to about ¾” 1″ as feed to finish mills. Fineness of grind is dependent upon the type of cement to be produced. Since fineness of grind falls below standard screen size accuracy, fineness of grind is determined by use of a “Wagner

  • Difference between Clinker and Cement Civil Engineering

    Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marble-sized pellets of clinker.
