    The heat generated in excess has to be dissipated so that mill discharge temperature is kept at a desired level (around 90-120°C) to prevent the deterioration of the quality of cement. The increase in temperature beyond 125°C leads to dehydration of gypsum which changes the property of setting of cement. The decrease in temperature below 90...

    Effects of the clinker gypsum grinding temperature upon. May 01, 1982 The temperature at which Portland clinker and gypsum are ground together to produce Portland cement is shown to influence the subsequent early hydration behaviour. Raising the grinding temperature from 90°C to 130°C and thence to 170°C has resulted in increased ettringite

  • Clinker quality depends on raw material composition.

    Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then are recombined into new compounds. The resulting clinker (rounded nodules

    A cement mill (or finish mill in High milling temperature causes this. On the other hand, if milling temperature is too low, insufficient rapidly soluble sulfate is available and this causes "flash set" an irreversible stiffening of the mix. Obtaining the optimum amount of rapidly soluble sulfate requires milling with a mill exit temperature within a few degrees of 115 °C. Where the

  • 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.
