摘要

A comminuting machine for trash has a generally closed housing provided at its top with an inlet and its bottom with an outlet. A rotor is provided in the housing and has at least one radially extending beater element that orbits on rotation of the rotor in a predetermined sense about a horizontal axis. An impact member is provided in the housing generally above the axis and spaced radially from the orbit of the beater element, the inlet being upstream of this impact member relative to the rotational sense of the rotor. A crusher plate is pivotally mounted in the housing generally below and downstream of the impact member and may be pivotally displaced between an effective position spaced radially relatively close to the rotor and an ineffective position radially relatively far from the rotor. A grate is displaceable through a sidewall of the housing between a withdrawn position outside the housing and an operative position under and relatively closely spaced from the rotor at the outlet. The side of the housing through which the grate is displaceable can be closed regardless of which position the grate is in and according to a special feature the rotor can be reversed so that the beater elements thereon can coact with a tearing comb mounted in the other sidewall of the housing for comminution of elastic or tough material.
