Abstract: The present invention relates to a separating device for crushing concrete. The separating device comprises at least two crusher members which, optionally in co-action with bounding elements situated adjacently of the at least two crusher members, define at their upper outer ends an inlet opening for concrete to be crushed and at their lower outer ends an outlet opening for crushed concrete or at least concrete fractions. The separating device further comprises a drive device adapted to move repetitively at least a part of one of the two crusher members in the direction away from and toward the other crusher member. Outlet restriction means are provided under the outlet opening to limit an outflow of crushed concrete and/or concrete fractions. The invention further relates to a method for crushing and separating a composite material, in particular concrete, into original components.

Abstract: The present invention relates to the field of rock crushers, in particular, rock crusher attachments for earth moving equipment or the like. The rock crusher attachment includes a front bucket portion configured for scooping rocks to be crushed and a rear crusher portion connected to and in communication with the rear of the bucket portion. The crusher portion includes a housing and a crushing assembly accommodated within the housing. The housing including a pair of spaced apart side panels. The crushing assembly has a lower jaw fixed between the side panels of the housing and an upper movable jaw mounted opposite and spaced apart from the lower jaw. The upper movable jaw assembly includes a support, an upper jaw plate attached to the underside of the support and a jaw-actuating drive assembly operable to urge the upper movable jaw assembly to move between an open jaw setting and a closed jaw setting. The support is pivotally connected between the side panels adjacent the front of the housing.

Abstract: A jaw crusher includes a machine with a moving base, a fixed base, a crush travel adjusting mechanism for pivotally coupling the top of a crush travel adjusting base to the machine by an eccentric sleeve, and an automatic crush gap adjusting mechanism. A toggle plate is installed between the crush travel adjusting base and the moving base. A pull rod of the moving base having a compression spring tightly presses front and rear ends of the toggle plate. The automatic crush gap adjusting mechanism fixes a steel slot of a stop plate and a pair of triangular wedge-shaped lumps to the position adjusting base of the machine, and the stop plate is installed between the steel slot and the crush travel adjusting base, and a pull rod of the adjusting base having a compression spring tightly presses both front and rear ends of the stop plate.

Abstract: A jaw crusher (10) includes a fixed jaw (16) and a swing jaw (18), which define a crushing chamber (26). The swing jaw (18) is mounted for cyclic movement in the direction of the fixed jaw (16), for crushing material between the two jaws. A cross beam (42) is adjustably received in apertures (40) provided in the walls (12, 14) of the frame (11). A toggle plate (54) is operatively arranged between the rear of the swing jaw (18) and the front of the cross beam (42). An hydraulic cylinder arrangement (60) includes a pair of cylinders mounted one on either side of the frame (11) in a respective aperture (40), in operative engagement with the rear of the cross beam (42). In use, the cylinders are pressurised to a predetermined value to provide an adjustable, pre-loaded reaction against the toggle plate (54), in line with the side walls.

Abstract: A jaw crusher is provided that includes a toggle plate holder mechanism, provided without increasing the overall height thereof, and a reaction force receiver link mechanism of an up-thrust type. A tension link mechanism acts as the toggle plate holder mechanism and includes a link having a tension link, a tension lever, a tension rod, and a tension spring. The layout angle of the tension link and tension rod can be changed freely by the tension lever.

Abstract: A jaw crusher capable of stable angle detection is provided. For this purpose, the jaw crusher includes a fixed jaw (35), a swing jaw (36) provided to oppose the fixed jaw, a frame (34) for supporting the fixed jaw and the swing jaw, and an outlet clearance adjusting mechanism (62) for adjusting an outlet clearance between the fixed jaw and the swing jaw, and the outlet clearance adjusting mechanism includes a connecting member (61) of which one end is made abut to or connected to the swing jaw, a rotatable rotary member (64) which is made abut to or connected to the other end of the connecting member, a driving mechanism (65) for rotating the rotary member, and angle detecting equipment (69) which is mounted to the frame and detects a rotation angle of the rotary member.

Abstract: A moving point involved in a movable teeth plate of an eccentric jaw crusher rotates on a closed loop, being called hysteresis curve in the specification. An angle between a major axis of the curve and the surface of a fixed teeth plate is a significant factor for crushing. The inventor found the fact that the alternation of the angle enables crushing ability to be rich. The angle is incontinuously varied. One of the positions at which a toggle plate is rotatably supported is selected. A larger angle is suitable for crushing harder materials, concrete for example, a small angle being suitable for soft materials, asphalt, for example. One self moving crusher can crush harder and soft materials at the same field where buildings are destroyed, or roads are repaired.

Abstract: A device for breaking stony material includes a frame, first and second substantially vertical crushing jaws with pressure surfaces connected to the frame so as to face each other and define an inlet opening for material to be broken close to their top ends and a discharge opening for broken material close to their bottom ends, a toggle lever system and pulling rod to which at least one crushing jaw is mounted for movement, and a hydraulic piston-cylinder for moving the toggle lever system and pulling rod so as to cause at least one of the crushing jaws to move in a first direction towards the other jaw and in a second direction transverse to the first.

Abstract: A jaw crusher for crushing stones or rocks of large mass in which a movable jaw is driven, on the fulcrum of a swingable supporting rod which supports the lower portion of said movable jaw, by means of swingable arms of a lever pivoted to the upper portion of the movable jaw through a lever mechanism which is moved by hydraulic cylinders. The stationary jaw is separated into two sections, so that the upper stationary jaw may be fixed at optional positions by virtue of means for freely advancing or withdrawing said jaw in horizontal directions.

Abstract: An apparatus for breaking heterogeneous material, in particular city solid wastes which are conveyed on a endless belt conveyor (27) which passes underneath the apparatus comprising a plurality of substantially parallel and ordinately closely juxtaposed to each other blades (15) and counterblades (8), this breaking system being supported by a guiding articulated quadrilateral rod system (13, 14, 18) adapted in unison and in sequence to open and raise to close counterblades (8) under the control of hydraulic cylinders (10), while a second auxiliary system (4, 25, 37, 40) provides to raise the first system at the end of the work stroke and to lower it again just before the beginning of its working stroke.
