Empty beverage container crusher has housing wall of concave curved shape having radius of curvature greater than radius of crushing roller and has free edge located within working range of roller

摘要

A crushing roller (1) in a housing (5) has axially spaced circles of alternating small and large projections (11,12). The housing wall (10) has a concave curved shape, whose radius of curvature is greater than the radius of the roller. The free edge of the housing wall lies within the working range of the roller, defining a tapered gap between the wall inner surface and the roller periphery (2). The gap becomes smallest when the projections overlap squeezing fins (23) at the housing, enabling crushing items to be discharged at the free edge.
