In a vertical roller mill the interparticle comminution takes place in a material filled gap between the rotating table and the grinding rollers. The mill feed is charged to the center of the table and moves by centrifugal forces and friction towards the table's edge. On its way it is nipped by two rollers installed at the outside rim of the table.
