Comminuting device

A comminuting device for solids-conducting liquids comprising:

• a housing with an inlet opening, an outlet opening and a housing interior extending from the inlet opening to the outlet opening;
• a first comminuting shaft extending through the housing interior and arranged to rotate about a first comminuting axis and onto which a plurality of first comminuting cutting elements spaced apart axially along the first comminuting axis is fastened;
• a second comminuting shaft extending through the housing interior and arranged to rotate about a second comminuting axis and onto which a plurality of second comminuting cutting elements spaced apart axially along the second comminuting axis is fastened;
• a drive device for driving the first and second comminuting cutting shafts in a rotational movement;
• a screening device having a screening wall comprising a plurality of slots arranged in the housing interior adjacent to the first comminuting shaft;
• and
• a clearing device comprising a plurality of clearing elements which can be moved relative to the screening wall along a movement path and which extend through the plurality of slots starting from a clearing shaft arranged on one side of the screening wall to at least one portion of the movement path, wherein the plurality of clearing elements are fastened to a clearing shaft basic body and at least two of the plurality of clearing elements extend at a different angle from one another from the clearing shaft base body.
