Abstract: A cutting mill for comminuting or fragmenting solid material and separating the same according to particle size is disclosed. The cutting mill comprises a housing having an upper pivotable part and a lower part, a bladed rotor rotatably mounted in the upper part and stator blades mounted in the upper part for cooperation with the rotor blades. The lower part has an opening covered by an easily replaceable sieve through with particles of a predetermined size are discharged. The particle size is determined by the spacing between the sieve and rotor blades, which spacing is determined by spacing elements mounted concentrically of the rotor at the ends thereof. The spacing elements are also provided with surfaces for setting a predetermined spacing between the rotor and stator blades.

Abstract: This disclosure relates to a band filter press for separating liquid and solid matter comprising a continuous filter band adapted to receive a mixture of liquid and solid matter and convey it through successive loading, pressing and unloading zones. The filter band is in the form of a hose having a bottom center strip and two cover strips fixedly connected to the edges of the bottom strip and partially covering the same. The cover strips, which may be either integrally formed with the center strip or provided in the form of separate strips which are connected to the center strip at its lateral edges, enclose acute angles with the center strip. The lateral extremities of the connection points between the cover strips and the center strip define finite longitudinally-extending edges by means of which lateral movement of the filter band may be determined and controlled.
