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).
