Abstract:
A slow speed, high torque shear technology is disclosed having optional configurations and attachments for its construction and methods for reconfiguring existing shears to improve performance, and maintenance economics (Figs. 1-45 and 49-69). A method is provided for the readily replacement of individual cutters and tooth modules, reconfiguration of cutter and tooth assemblies in a mix and match manner, in combination with matching anvils having replacement cutting elements with multiple cutting faces (Figs. 1-45 and 49-69). Alternative embodiments are provided illustrating methods of configuration of various types of cutting elements and material feed systems (Figs. 46-48B). Methods for converting a rough cut shear to a fine particle shear and then to a granulator as well as a method for rejecting unprocessable material is also disclosed.
Abstract:
A mill (10) for grinding garbage is disclosed including an octogonal shaped grinding chamber (26). Grinding rotors (48-50) are rotatably fixed to a rotatable shaft (44). An impeller rotor (51) is also rotatably fixed to the shaft (44) below the grinding rotors (48-50). The impeller rotor (51) discharges a stream of air, entrapped material, and projectiles into a projectile deflection device (182) which includes an upwardly sloping bottom plate (202) which deflects the projectiles into an end plate (204) to reduce the kinetic energy thereof. The air stream and entrapped material pass from the projectile deflection device (182) into a plenum (210) which reduces the velocity of the air stream to release much of the entrapped material, with the material release being enhanced by baffles (224) providing a tortuous path for the air stream in the plenum (210) before it enters a cyclonic material separator (216). Material anti-wrap provisions (140) in the form of wing plates (152, 154, 156) radially extending from semicylindrical carriers (142a, 142b) are provided between the top plate (28) and the first rotor (48), between the first and second rotors (48, 49), and between the second and third rotors (49, 50). Deflector bars (164) are attached to the axial ends of the wing plates (152, 154, 156) to prevent migration of any wrapped material therebeyond. The upper axial ends of the anti-wrap provisions (140) are positioned within the axial extent of cylindrical deflectors (168) mounted to the top plate (28) and the first and second rotors (48, 49).
Abstract:
A pulverizer for reducing a size of input material particles, the pulverizer comprising: a housing, a rotatable shaft with rotor arms and at least one airflow deflector cooperating with the rotor arms to deflect airflow within the pulverizer so as to form at least two overlapping vortices within the interior chamber such that input material particles in suspension in both overlapping vortices collide with each other to be thereby pulverized; also a pulverizer comprising a housing liner including a plurality of housing liner portions attached to and extending along a outer structural wall of the housing; also a pulverizer comprising a housing sidewall having an outer structural wall comprising a plurality of wall sections; also a pulverizer with canted rotor arms and a pulverizer comprising rotor arms with removable wear pads; also an anti-caking device for a vessel such as a pulverizer.
Abstract:
A rotor positioning device (113) to adjust a rotational position of a rotor (4) of a horizontal shaft impact crusher (1). The device is mountable to an external region of a main frame of a crusher so as to releasably couple to an exposed end (400) of a main shaft (6) of the rotor (4). The device comprises a shaft engager capable of being moved to and from engaging contact with the rotor shaft end (400). A drive component (108) provides rotational drive of a rod (104) to impart rotational adjustment of the position of the rotor shaft (6).
Abstract:
Discharge grate components for reducing machines including stops to inhibit pokers within the grate so that the pokers are not ejected from the grate with a high velocity.
Abstract:
An apparatus comprising a rotor position detection unit (30) with a sensor (32), configured to detect an angular position of a rotor (13) of a horizontal shaft impact crusher (200), the rotor having attached thereon a group of hammers (14,15,16,17). A motor control system is (130) configured to change the rotation speed of the rotor (13) and an automation and control system (125) is configured to control the motor control system (130) in response to the detected angular position of the rotor (13). The rotor position detection unit (30) is configured to detect a first and second angular position of the rotor (13) corresponding to a first and second position (50) of a hammer (14,15,16,17) of the group of hammers attached to the rotor (13). The motor control system (130) comprises a frequency converter (135) and a brake (140) configured to enable the stopping of the rotor (13).
Abstract:
L'invention est un perfectionnement des broyeurs existant qui permet une baisse significative du coût d'exploitation desdits broyeurs en permettant entre autres une économie substantielle de la matière dans laquelle les protections des rotors desdits broyeurs sont fabriquées. L'invention a pour objet un bloc de protection pour rotor de broyeur de matériau, particulièrement les rotors de broyeurs de ferrailles, comportant une première pièce ou plaque de blindage (2.2) comportant elle-même, solidarisé de manière amovible ou inamovible sur sa face interne un premier moyen de fixation (2.3); et une seconde pièce, indépendante de la première pièce, formant un second moyen de fixation (2.4).
Abstract:
La présente invention a pour objet un pré-broyeur ou pré- déchiqueteur de matériaux de toutes origines en vue du déchiquetage au moyen de concasseurs ou de broyeurs à marteaux, ou analogues. Pré -broyeur ou pré-déchiqueteur caractérisé en ce qu'il est de faible encombrement et modulable et est essentiellement constitué par au moins un outil de déchiquetage (1) et par au moins un moyen d'entraînement (2) de cet outil (1), l'ensemble ainsi constitué étant monté sur un châssis (3), une goulotte d'alimentation ou un autre support, directement par l'intermédiaire du moyen d'entraînement (2) ou d'un support de ce dernier.
