Embodiments disclosed herein provide a cone crusher having a bowl support and a stationary frame to which the bowl support may be mounted, the frame including an outwardly-facing threaded portion. A wedge structure may be disposed between the bowl support and the threaded portion of the frame, the wedge structure including an inwardly-facing threaded portion, the threads of which complement the outwardly facing threaded portion of the frame. Means may be provided for exerting an upward force on the wedge structure to move the wedge structure from an original position to an operational position during crushing operations and means may be provided for exerting a downward force on the wedge structure to return the wedge ring to the original position following crushing operations.

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.

A method for operating an aggregate material processing plant according to two alternative modes of operation. In a first operating mode, unprocessed aggregate material is deposited onto a crusher feed conveyor and then fed to a crusher. The crusher produces crushed aggregate material, which is conveyed by a collection conveyor to a vibratory screen assembly at a first speed. The vibratory screen assembly sizes aggregate material deposited onto an upper screen deck thereof. Unscreened aggregate material is conveyed by a transfer conveyor to the crusher feed conveyor. In a second operating mode, unprocessed aggregate material is deposited onto the vibratory screen assembly, which sizes the aggregate material. The transfer conveyor conveys unscreened aggregate material to the crusher feed conveyor. The crusher feed conveyor feeds aggregate material to the crusher, which produces crushed aggregate material. The collection conveyor conveys crushed aggregate material to the vibratory screen assembly at a second speed.

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.

Embodiments disclosed herein provide a cone crusher having a mantle and a rotating eccentric that causes the mantle to gyrate from side to side with respect to a stationary frame to which is mounted a crusher lining. The cone crusher may include a thrust bearing having a first bearing ring rotating with the eccentric and a second bearing ring mounted to the frame, the first and second bearing rings being disposed immediately adjacent and facing each other, one of the rings having a plurality of spaced oil feeds and a first and a second set of ramps on a surface facing the other ring. The first and second set of ramps extend upwardly from each of the oil feeds in opposite circumferential directions.

A gyratory or cone crusher includes a measuring apparatus suitable for measuring load of the crusher, a first element placed on a main shaft of the crusher and a first detector suitable for detecting the first element which first detector provides a trigger starting a measurement revolution, and at least one second element placed on a drive shaft of the crusher and a second detector suitable for detecting the second element and providing a trigger corresponding to a certain rotational position of an inner blade of the crusher. The system includes an output to a screen for presenting the loads or averages of the loads corresponding to rotational positions of the inner blade of the crusher. Detections of the monitoring system can be used for controlling and monitoring a crushing event, such as by changing an area or a location of a feed opening of the crusher.

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.
