The two counter-rotating rollers of the roller press exert very high pressure on the material, effectively crushing and weakening the particles. Microcracks are created and make it easier to grind the particles finely. Used as a pre-grinding system in ball mill circuits, for example, production increases of up to 40 % and more can be achieved.
