A disintegrating apparatus comprising a material infeed hopper (2) and a rotatable shaft (4) mounted in an elongate opening (3) in a frame (1) disposed under the hopper. The shaft comprises a plurality of helically arranged and axially spaced-apart working means (5) which cooperate with holding-up means (12) in the area of a front longitudinal side edge of the opening (3). The hopper (2) is hingedly connected to the frame so that, if necessary, the hopper can be swung up while to give access to the shaft. In addition to said holding-up means (12), the apparatus comprises a second set of holding-up means (16) mounted at the rear longitudinal side edge (11) of the opening (3) and adapted to prevent large objects from passing down the back way between the shaft (4) and the rear longitudinal side edge (11) and to cooperate with the working means (5) upon reversal of the direction of shaft rotation, so as to provide at least a certain degree of disintegration of material also in reversed operation. |
