Dear mb14,

As per my experience it is not possible. I have calculated by considering cement mill somewhere in -40 C climatic condition than also i can reduce only 25 % of present water consumption.

Vikpro,

You need to perform a full heat and mass balance calculation to decide about that.
It is obvious that the amount of fresh air should play a role as well as the specific power consumption and the temperatures of your raw materials and several other parameters.
If your clinker is hot, you might consider some cooling before the mill.
The rate of air recirculation on the separator is an important parameter as it is related to the amount of fresh air.
It also depends on if you have wet material entering your mill.
