There is disclosed a shredder unit (10) which is especially suitable for shredding scrap tyres, and which comprises a base (11), a pair of drive shafts (12) mounted on the base (11) with their axes of rotation extending substantially horizontal, and material-shredding rotary cutters (13) mounted on the shafts (12) for rotation therewith. The shafts (12) are laterally spaced from each other to define a space (14) for receiving material to be shredded, and bearing housings (15) rotatably mount the ends of the shafts (12) by means of bearing assemblies which include fabric bearings. The bearing housings (15), the shafts (12) and the cutters mounted thereon form a unit which is bodily mountable in, and removable from a mounting (16) provided for the unit in the base frame (11), whereby the unit effectively takes the form of a cartridge unit which can be removed entirely in the event of a fault or undue wear developing in any of the components, and a replacement unit can then be mounted in place in a relatively short period. |
