摘要： A gyratory crusher including a main shaft that can be installed into a main frame. The gyratory crusher include an alignment system having a stationary dust collar and a separate alignment ring attached to the dust collar. The alignment ring includes a tapered contact surface extending from a lower outer edge to a top edge to help guide a dust seal past the alignment ring and into contact with an outer surface of the dust collar. The dust seal is received within a receiving cavity of a dust seal retainer mounted to the main shaft of the crusher. A series of alignment openings extend through the dust seal retainer to provide access to an outer edge of the dust seal. The position of the dust seal can be adjusted based upon measurements of the outer edge. The main shaft includes a chamfer on the lower end guide the main shaft into a bushing assembly.

摘要： A system for monitoring at least one motion parameter of the main shaft of a gyratory or cone crusher. The system includes a sensor, such as a magnetometer, positioned within close proximity to a magnetic element, such as a lifting lug, formed on a top end of the main shaft. When the main shaft rotates or moves vertically, the movement creates a change in the magnetic flux, which is sensed by the magnetometer. The change in the magnetic flux is sensed by the magnetometer and an output signal is generated. A controller receives the output signal and determines at least one motion parameter based upon the detected changes in the magnetic flux. In one embodiment, a permanent magnet can be the magnetic element or can be inserted into the lifting lug to enhance the magnetic flux changes caused by the rotational movement or vertical movement of the main shaft.

摘要： A crusher device such as a cone or gyratory crusher is disclosed. The crusher device includes a shaft defining a first direction parallel to its length. The shaft includes an upper shaft end, a crusher head, and an overload safety device that couples the crusher head to the upper shaft end. The overload safety device includes a biasing device configured to bias the crusher head away from the upper shaft end in the first direction. The overload safety device is configured to permit displacement of the crusher head along the first direction relative to the shaft in response to a force acting on the crusher head in the first direction.

摘要： A bowl liner for use in a crusher that is comprised of a support cassette and a plurality of bowl liner sections mounted to the support cassette. Each of the bowl liner sections is mounted along an inner surface of the support cassette. Once the bowl liner sections are positioned along the inner surface of the support cassette, a plurality of support plates are used to support the bowl liner sections on the support cassette. An epoxy material can be utilized to further attach the plurality of bowl liner sections to the support cassette such that the bowl liner sections are held securely in place during use. The bowl liner can be replaced in the crusher as a single unit. After use, the bowl liner sections can be removed from the support cassette and the support cassette can be reused with another set of bowl liner sections.

摘要： An eccentric assembly for use in a gyratory or cone crusher is provided. The gyratory or cone crusher includes a main shaft having a longitudinal extension along a central axis of the crusher, a head assembly including a crushing head provided with a first crushing shell, and a frame provided with a second crushing shell, wherein the first and second crushing shells between them define a crushing gap. The eccentric assembly is provided with an inner circumferential surface and an outer circumferential surface eccentrically arranged relative to the inner circumferential surface, wherein the inner circumferential surface of the eccentric assembly is arranged for being journalled to the main shaft so that the eccentric assembly is adapted to rotate about said central axis, and wherein the outer circumferential surface of the eccentric assembly is arranged for being journalled to the crushing head. The eccentric assembly includes a first eccentric part and a second eccentric part which is configured for being located at a distance from the first eccentric part in a direction along the central axis.

摘要： A method, crusher, computer program and crushing plant, in which bridging generated on an arm is detected in a crusher that has a body, an outer wear part fixed to the body, an outer wear part fixed to the body; a support cone rotatable inside the body via a main shaft); an inner wear part on a cone surface of the support cone; and a support of the support cone. The support contains a group of arms inside the body and extending inwards from the body; a main shaft radially supported to the arms; and a thrust bearer supported by the arms for supporting the main shaft and for axially supporting the support cone via the main shaft. The crusher crushes mineral material between the inner wear part and the outer wear part. Measurement information is received describing stress of the support of the support cone; and bridging formed onto an arm is detected from the measurement information.

摘要： The present disclosure provides a generally cylindrical bowl support for a cone crusher which includes a plurality of evenly, circumferentially spaced ears around the periphery of the support. The ears are designed to have clamping cylinders mounted thereto to provide protection from tramp iron and the like passing through the cone crusher. A plurality of thickened ribs are defined in the support, at least some of the thickened ribs extending downwardly from the ears to form abutting polygon configurations to spread and absorb forces from a crushing operation. Other ones of the ribs define at least one circumferentially-extending, continuous ring forming portions of the polygons.

摘要： A method for lifting an inner wear part of a gyratory or cone crusher and an inner wear part lifting tool for use with the method. The gyratory or cone crusher has a frame, an outer wear part fixable to the frame and the inner wear part fixable to a support cone of the crusher which outer and inner wear part define a crushing chamber. The inner wear part has an inner surface including a first inner support surface arranged, in a crushing phase, to be supported by a first counter surface of the support cone. In a first phase, a lifting arm of a lifting tool is arranged inside the inner wear part and under the inner surface of the inner wear part. In a second phase, an upper second counter surface of the lifting arm is coupled with a second inner support surface of the inner wear part.

摘要： A cone crusher apparatus having a bowl liner removably mounted within a bowl. A wedge is radially adjustable between an inside surface of the bowl and an outside surface of the bowl liner. The wedge moves radially between a rotation-preventing position and a rotation-permitting position. In the rotation-preventing position, the wedge is in simultaneous abutment with the bowl and bowl liner and through that simultaneous abutment immediately develops a maximum holding force such that relative motion between the bowl liner and bowl in a first rotational direction is prevented. In the rotation-permitting position, the wedge is not in simultaneous abutment with the bowl and bowl liner and at least some relative motion between the bowl liner and bowl in the first rotational direction is permitted.
