    Patent number: 8910891
    Abstract: Comminution apparatus is described which is tailored for the processing of green, soft, and fibrous waste. Inner and outer comminution drums bear projecting macerating features which can progressively interact to provide a shearing action on material on waste within the outer comminution drum. Screening apertures on the outer comminution drum allow for the exit of comminuted material.

  • INTEGRITY OF THE UNION BETWEEN COMPONENTS
    Publication number: 20120180299
    Abstract: An improved method of shrink fit assembly of two components increases resistance to torsional and/or axial loads without the need for a separate key element. Use of a roughened surface, in combination with a softer deformable material, creates a keyed type interaction at the contact areas of the shrink fitted components. One of the shrink fitted components may include the softer material, though intermediate layers and sleeves can be used.
