cement industry and leads to efciency and production
increases.

Any attempt to add the energy consumption of an oxy-
gen production facility begins with an analysis of the
energy consumption of the process. Electrical energy
is consumed at various stages in the process. The tech-
nologies used include crushing using a roller crusher,
raw meal grinding in a vertical mill, a dry (short) precal-
ciner kiln, and nish grinding in a ball mill/separator.
