<p>Device for breaking stony material comprising a frame (10), first (11) and (12) second substantially vertical crushing jaws connected to said frame (10) and comprising pressure surfaces facing each other, which jaws define between them an inlet opening (14) close to their top end for material to be broken and a discharge opening (15) close to their bottom end for broken material, guiding means (16) on which at least one crushing jaw is mounted for movement, and drive means (19) for moving the crushing jaws relative to each other in a direction towards each other. The guiding means (16) also impose on said crushing jaws (11, 12) during their movement towards each other a relative movement transversely of said pressure surfaces.</p> |
