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 complemen
tal to said projection (6) is less that the distance between the
central axes (9, 10) of the rolls.
