Abstract
An article breaking device, particularly a glassware breaking device for making cullet, is described. The articles to be broken pass down a chute into a downwardly open chamber. Within the chamber is a rotating member which is not circular in horizontal cross-section and which is rotated at high speed around a vertical axis. The articles to be broken impact on the member, are broken and the broken pieces fall out of the open base of the chamber. The rotating member is preferably frustoconical with a plurality of vertically running external ribs and a plurality of horizontally extending blades.
Claims5
Apparatus for fracturing glassware into cullet comprising:
- an upwardly and inwardly tapering impact member of noncircular horizontal cross-section mounted for rotation in a given direction about a vertical axis, said impact member including generally vertically extending ribs which have side surfaces facing generally in said given direction;
- a housing having a side wall with a generally smooth inner surface, said side wall surrounding and horizontally spaced from said impact member and extending downwardly beyond the lower edge of said impact member whereby a generally annular space is formed between said side wall and the lower edge of said impact member;
- means for rotating said impact member about said vertical axis in said given direction;
- and glassware feed means including a guide chute having a guide surface inclined downwardly and inwardly toward the side of said impact member for directing glassware issuing from the chute onto the side of said impact member, the arrangement of impact member, housing side wall and chute being such that the glassware is fractured into cullet upon contact with said impact member and falls downwardly away from said impact member and through said generally annular space.
