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.

Definition and overview of Vertical Axis Wind Turbines (VAWTs) The overview and definition of VAWTs can help us understand how these turbines function. A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set vertically. Unlike horizontal-axis wind turbines (HAWTs), VAWTs can operate regardless …
