    The insulation is on the inside, the steel on the outside needs to be cold to bear the load. This is a limiting factor for indirectly fired rotary kilns.

    They do all of what you say, generally really well optimized, since even tiny improvements mean large savings.

        Will do, but cement plants are actually not really the stuff I work on, since there are only so many and they already know what rotary kiln they want :D Those things are used all over the place from tiny (few cm diameter, less than a meter long) to massive like for cement. From high tech catalysts or activated carbon to recycling processes and every step in-between.
