Abstract: The disclosure relates to a sieve mill including a basket having a curved inner side for supporting a sieve which rests on the curved inner side of the sieve basket, and two longitudinal edges which are parallel and opposite each other, a material inlet arranged above the sieve and a cylindrical rotor arranged such that it can rotate inside the sieve basket. A longitudinal edge of the sieve is arranged in a first retaining bar having a first positioning recess for receiving the longitudinal edge, and another longitudinal edge is arranged in a second retaining bar having a second positioning recess for receiving the other longitudinal edge, the second retaining bar can pivot between an open position in which the second positioning recess can withdraw and feed the associated longitudinal edge, and a closed position in which the second positioning recess exerts pressure upon the longitudinal edge.

Abstract: The invention relates to a device having two rotational shafts which are arranged at least essentially parallel to each other and associated with rotational axes (13a, 15a) separated by means of an adjustable distance. The shafts extend respectively through a wall (28) which separates a drive side from the product side, and are sealed with respect to the wall (28).

Abstract: The invention relates to a sieve mill (10) comprising a basket (12) having a curved inner side for supporting a sieve (14) which rests on the curved inner side of the sieve basket (12), and two longitudinal edges (32, 34) which are parallel and opposite each other, also comprising a material inlet (18) arranged above the sieve (14) and a cylindrical rotor (16) which is arranged such that it can rotate inside the sieve basket (12).

Abstract: A method and an apparatus for treating and utilizing waste materials and mixtures thereof in multiple steps resulting in a high-yield utilization particularly of organic components of the waste for generating kinetically useful energy. The waste materials are sorted by classes, principally between organic and non-organic, e.g. metallic and ceramic, substances. The organic substances are briquetted and gasified, the produced gas being utilized for the direct and indirect generation of electricity and heat.
