A disintegrator is composed of (1) a mulch plate with one or more raised diffusers composed of evenly spaced bars rising from the plate with spaces between them, and (2) one or more mulch bars each composed of a bar with teeth projecting from one surface spaced to pass through the spaces between the bars of the diffusers. The mulch bar is positioned to rotate with respect to a fixed location on the mulch plate so that the teeth will pass through the spaces between the bars of the one or more diffusers. The plate may be perforated or imperforate. In the preferred disintegrator, one or more narrow portions of the mulch plate in areas extending substantially radially from said fixed location are fabricated into diffusers. The bars and spaces of each diffuser are arranged substantially circumferentially of said fixed location so that the teeth of the mulch bar pass through them as it is rotated. The spaces between the bars of the diffuser extend through the plate, either as one long opening under the entire diffuser (which is the case when the diffuser is fabricated separately from the plate) or as separate openings (which may be the case when the diffuser is formed from the plate).
