Study on energy use and carbon emission from …
However, GBFS was found to demand more energy compared to fly ash as it should undergo quenching, drying, crushing and grinding process before actually it is used in cement. It is also to be noted that the use of vertical roller mill (VRM) with closed circuit for cement milling in place of ball mills with open circuit minimizes the energy demand.
Operational parameters affecting the vertical roller mill …
In literature, there are many studies performed in cement plants on comparison of conventional grinding systems and vertical roller mills in terms of energy consumption. It was noticed that 30% energy saving could be provided by VRM for cement grinding ( Schaefer, 2002 ).
Roller mills
For a grinding plant designed for an output of 80 t of portland cement per hour a roller mill with a grinding bowl diameter of 4.1 m is required. The total power consumption of the grinding plant is 26.5 kWh/t, cor responding to a 20 % saving in comparison with a plant incorporating a ball mill.
