Abstract 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.

The roller mills are the primary grinders in the flour mill (Posner and Hibbs 2005). In a roller mill, particles are subjected to shear and compressive forces (Haque 1991 ). Segregation between the kernel parts occurs in plansifters, where sieves separate particles of different size, and in purifiers, where sieves and air-flow separate ...
