Abstract
In order to assure that an adequately small delivery granulation is offered to the nip of a two-roller machine, preferably a high-pressure roller press for interparticle crushing, namely for an optimum draw-in of the granular material, it is inventively proposed that a sieve means to be arranged in the product delivery shaft of the two-roller machine and that the oversized sieve particles be comminuted with a crushing roller that is likewise arranged in the product delivery shaft and that the comminuted particles then be presented to the high pressure nip for further interparticle crushing.
