The invention relates to a cutting device for macerating a free-flowing fluid-solid mixture, having a knife rotor which is mounted in such a manner as to be able to rotate relative to a cutting sieve. Said knife rotor abuts the cutting sieve axially with respect to the direction of its axis of rotation, and is pretensioned against the cutting sieve in the axial dimension. According to the invention, at least one clearance space is included, wherein the same is bounded by at least one first and one second surface, and the first surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the knife rotor, the second surface is arranged in a manner such that it cannot be displaced in the axial dimension toward the cutting sieve, and the first and the second surfaces are arranged such that they cannot rotate about the axis of rotation of the knife rotor with respect to each other. At least one freewheel body is arranged in the at least one clearance space, and is pretensioned in the axial dimension to abut the first and the second surface in a second pretensioning direction, and the first and the second surfaces are designed at least partially in such a manner that the radial gap between the first and the second surface narrows in the direction of the second pretensioning direction, whereby a relative movement in the axial dimension between the knife rotor and the cutting sieve in the direction opposite that of the first pretensioning direction is prevented. |
