A comminuting device includes a comminuting chamber which has a bottom wall and a circumferential wall which extends upwards from the bottom wall. The device also includes a rotatably driven drive shaft which extends essentially orthogonal to the bottom wall, and at least one comminuting element which is disposed next to the bottom wall. This at least one comminuting element can be made to perform a rotary movement about the drive shaft by the drive shaft. A plurality of additional comminuting elements which can be made to perform a rotary or revolving movement about the drive shaft (22) by means of the drive shaft are arranged above the at least one comminuting element comminuting element disposed next to the bottom wall.
