  Process technology for efficient and sustainable cement production ...

  2015121 · Process-wise the technology for these new cement types is in principle available; various kiln systems including their coolers exist. They differ from conventional clinker production due to the fact that the stabilisation of the major mineralogical phase requires e.g. very specific temperature profiles in the kiln or cooling conditions [60].
