    The result is that the hot gas flow from the lower cyclone tube can be short-circuited into the superior cyclone tube, resulting in the secondary flying of the separated raw material powder and reducing the separation efficiency of the superior cyclone tube. When the raw material powder from the upper cyclone tube enters the heat exchange pipe ...

  • 3.4 Burning in a kiln – formation of cement clinker

    3.4 Burning in a kiln – formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix.

    Chlorine induced high temperature corrosion kinetics in the preheater cyclone reduces the service life of dip tube material. Portland cement is manufactured in a rotary kiln. The rotation of the kiln causes the raw material to gradually pass along and undergo chemical reaction from where it enters the cooler.
