dry grinding iron ore energy consumption:

Research of iron ore grinding in a vertical-roller-mill ...

The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.

Method to estimate the specific energy consumption of
