An insert for covering one or more selected surfaces of a discharge end assembly including a discharge end wall of a mill shell partially defined by an outer perimeter wall thereof and a number of pulp lifters mounted on the discharge end wall. The insert is formed to cover the selected surfaces to mitigate wear to which the selected surfaces are subjected when the insert is located in a predetermined position relative to the selected surfaces.

The present invention relates to a counter-blade, in particular, for a wood chipper, for producing wood chips, comprising at least one cutting edge made of a hard material, and a support surface leading to the cutting edge. According to the present invention, the cutting edge is made up of a plurality of hard material elements that are arranged next to one another along the cutting edge on a main member. This results in a counter-blade having a long service life.

A locking nut (10) and washer (12) for use with a threaded bolt. The locking nut (10) has a tool engaging portion (14), a threaded aperture (20), and a washer engaging portion (18). The washer (12) has a locking nut engaging portion (28, 36) and an aperture (32). When the washer engaging portion (18) engages the locking nut engaging portion (28, 36), the threaded aperture (20) and the aperture (32) align to be at least substantially concentric so as to receive the threaded bolt. In this manner, when the tool engaging portion (14) is appropriately manipulated to force the locking nut (10) in a first direction along the threaded bolt, the engagement between the tool engaging portion (14) and the locking nut engaging portion (28, 36) also causes the washer (12) to move along the threaded bolt in the same direction.

The disclosure relates to an impact crusher having a rotor that has a plurality of rotor disks, wherein each rotor disk has a plurality of edge recesses distributed along its outer circumference. The edge recesses are arranged in alignment with one another and are designed to hold a blow bar. Each edge recess has a first side wall, a second side wall and a bottom wall. A clamping wedge with a clamping wall is arranged on the second side wall of each edge recess. The clamping wedge is fixable to the second side wall in a clamping position in which the clamping wall of the clamping wedge is arranged so as to clamp the blow bar. The clamping wedge is mounted on the second side wall so as to be movable from the clamping position into a maintenance position, in which the clamping wall of the clamping wedge is arranged to release the blow bar.

A tool for a retainer assembly of a gyratory crusher, the tool being arranged around a shaft of the crusher on top of the retainer assembly. The tool includes a first plate arranged on top of a second plate. A first and second actuator are mounted at a periphery of the second plate on opposite sides thereof. A first and second lever arm are mounted on the first plate and in connection to the first and second actuator. A first and a second movable spigot are mounted on the first plate in connection to the first and second lever arms. Pins are mounted on the lower side of the second plate in order for the tool to fit with the retainer assembly. A retainer assembly to be used in connection to the tool, and a method for using a tool in order to fasten a retainer assembly is also provided.

Provided are a combined roller sleeve, a method for preparing the combined roller sleeve, and a press roller. The combined roller sleeve includes a first roller sleeve and a second roller sleeve that are separately formed and connected to each other. Connected end surfaces of the first roller sleeve and the second roller sleeve each have a notch in a circumferential direction. The notches are formed as a groove at a connection between the first roller sleeve and the second roller sleeve. First hard studs are embedded in the groove. Gaps between the first hard studs and between each of the first hard studs and a wall of the groove are filled with metallic surfacing layers.

A method and machine (10) for stud installation are described. The machine comprises: a support arrangement (20) configured to support a tyre (14) and a shaft (12) on which the tyre is mounted for angular displacement about a longitudinal axis of rotation, and a stud insertion arrangement (22), at least part of which is displaceable relative to a tyre supported on the support arrangement, and which is configured to insert studs into holes in the tyre.

The present invention is related to hierarchical composite wear component comprising a reinforced part, said reinforced part comprising a reinforcement of a triply periodic minimal surface ceramic lattice structure, said structure comprising multiple cell units, said cell units comprising voids and micro-porous ceramic cell walls, the micro-pores of the cell walls comprising a sinter metal or a cast metal, the ceramic lattice structure being embedded in a bi-continuous structure with a cast metal matrix.

A wear plate assembly for an agricultural harvester including a support element having a number of lateral regions, each lateral region being provided with a plurality of first engagement features, one or more replaceable wear plates provided on one side with a plurality of second engagement features for engagement with the first engagement features, and a plurality of fastenings to secure each replaceable wear plate to the support through the engagement features.

A wear protection component includes an elastic material layer and a reinforcing support. The elastic material layer is bonded to the reinforcing support, and the wear protection component is bent into a curved shape. In an area delimited by an outer periphery of the reinforcing support, the wear protection component includes one or more local stress relief areas in which the elastic material layer is not bonded to the reinforcing support.
