(54) Apparatus and method for fragmenting frangible objects


(57) Apparatus for fragmenting brittle or other breakable objects, such as scrap metal castings or rock, includes a pivoted first crushing member (20, 50) and a fixed second crushing member (14,54). The first member has a plurality of crushing regions (23, 24, 27) located at various distances from the pivot axis (26), which is offset, so that each successive crushing region approaches the second member closer than the preceding crushing region. The object is fragmented by a combination of compression and shear forces. Projections (27) may be provided to localise the forces, and loose members such as chains (56) may be utilised to dislodge adherent fragments from within the apparatus.
