Abstract
In a hammer mill (1) for shredding scrap metal, comprising a hammer rotor (5) carrying swing-mounted hammers (12) and arranged to rotate in a housing (2) having an inlet opening (14) for material located on the upwardly-rotating side of the rotor, a screening grid (33) and an impact chute (26) open to the hammer rotor, the risk of breakdown of the hammer mill is reduced without impairing its shredding performance by forming the wall of the impact chute (26) on the side opposite to the inlet opening (14), together with a screening grid (33) extending to the bottom (32) of the housing, as a resiliently yielding outlet wall (28) that can automatically swing outwards.
