High pressure grinding is achieved by an advanced type of grinding roll. Contrary to conventional crushing rolls the particles are broken by compression in a packed particle bed and not by direct nipping of the particles between the two rolls. This particle bed is created between two choke-fed counter-rotating rolls.
