The comminution and distribution device according to the invention can be used to crush comminutable, pumpable materials, in particular mechanically dewatered slurry, into roughly the same sized pieces, and feed them in controllable quantities to a downstream device, e.g., a dryer. To this end, the slurry is conveyed through a gap formed by two oppositely rotatable parts. In preferred embodiments of the device according to the invention, both parts exhibit recesses on the side facing the gap, which are designed in such a way that, when the two parts are turned opposite each other in the preset rotational direction, slurry strands with periodically alternating areas with smaller and larger cross sections are formed, transported outside and split at locations exhibiting smaller cross sections.
A comminution and distribution device comprising a slurry supply line supplying comminutable, pumpable materials, to two parts forming a gap (4) therebetween, in which materials to be comminuted are conveyed toward an outside of the device through gap (4), wherein at least one part of the two parts that form the gap (4) is rotatable along a rotational axis (10), and wherein at least one recess (5) is incorporated in a surface of at least one part of the two parts that form the gap (4), said surface facing the gap, said recess starting at an area near rotational axis (10) and proceeding up to an edge of the part containing the recess, wherein an edge of one of the two parts that form the gap (4) projects over an edge of the other part, and that at least one section of the two parts that form the gap (4) is provided on the edge with teeth (6) facing the gap (4).
