ABSTRACT A method and a machine for comminuting precompacted or board-like cellulose material, especially for feeding a stoker plant, for example, while using a roll pair (4, 5) for receiving the material, where each roll (e.g. 4) is provided about its periphery with alternating projections (6) and depressions (7) corresponding to depressions (7) and projections (6) on the second roll (5) in each such pair, which is driven with the same peripheral velocity for both rolls (4, 5). Said projections (6) and depressions (7) along the periphery and axially can have pyramidal shape, for example, the distance between the rolls being adjustable such that the sum of the radius to the crest of a projection (6) on one roll (4) and the radius to the bottom of a depression (7) on the corresponding roll (5) and complemental to said projection (-6) is less that the distance between the central axes (9, 10) of the rolls.
