<p>Crushing plant comprising a cage (21) within which there rotates at high speed a generally cylindrical rotor (3), on the periphery of which there are provided longitudinal hinge pins (32) for crushing hammers (30), in which the retention seats (5; 55) for said pins each open into the outer surface of the rotor via a respective generally radial cut (7) having, at least in proximity to its connection to said seat, a width less than the pin diameter, said pins presenting, at least in correspondence with those portions contained in said seat, a non-circular cross-section, one transverse dimension of which is slightly less than said width, said pins being arranged to rotate within their seats between a first angular position or locked position, and a second angular position or released position, in which said one transverse dimension of said non-circular cross-section lies substantially parallel to, and respectively generally oblique to, said cut. <IMAGE></p> |
