1. An apparatus (1) for treating material, comprising:
- a feed device (4), which is provided with a receiving opening for feeding the material;
at least two shafts (14, 15), which are disposed parallel to one another and are seated to rotate, and are connected to a drive device (6) that is designed to set the shafts (14, 15) into a rotational movement in opposite directions; and
elements (23) for exerting a notch effect on brittle components of the material to be reduced, the elements being connected to the shafts (14, 15) for forming cracking mechanism (5), wherein the elements (23) that exert a notch effect are disposed in groups at locations on the shafts (14, 15) that are axially spaced (16, 17) from one another, the elements (23) of a group (31, 32, 33) that exert a notch effect are disposed on a circle that is coaxial relative to the shaft (14, 15), and the elements (23) of adjacent groups (31, 32, 33) that exert a notch effect are disposed on circles having different diameters.

Abstract
An apparatus suitable for treating mineral material, particularly excavated earth, has two rollers that rotate in opposite directions, on which a plurality of elements is disposed, the elements serving to transport and reduce the material in case its particle size is too large. Elements that are designed to exert a notch effect onto particle sizes larger than a minimum size are provided for reducing brittle and large-particle components of the mineral material, in particular. The reduction by means of the notch effect has been proven to save energy and subject machines to low wear. The elements that produce the notch effect can also reduce wood (tree stumps).
