ABSTRACT:
A method and apparatus for continuous pressure comminution of brittle grinding stock such as cement clinker wherein simultaneous operations of unit grain comminution and product bed comminution are carried out in the roller gap of the same roller machine in such a manner that the grinding stock is first precomminuted by means of the unit grain comminution in a wider roller gap and immediately thereafter, the grinding stock fragments produced in the unit grain comminution are further comminuted by the technique of product bed comminution in the region of the narrowest roller gap. The continuous pressure comminution is characterized by a high pressure of more than 2 metric tons per centimeter of roller length, with a sifter being provided after the pressure roller.
