A tool for processing abrasive materials, in particular rocks, sand or ores, may include a main tool body and a hard metal plate positioned on the main tool body. A build-up weld may be applied to a surface of the hard metal plate and to the main tool body to bond the hard metal plate to the main tool body. Further, a method for producing or treating such a tool may involve positioning the hard metal plate on the main tool body and applying a build-up weld to the hard metal plate and the main tool body such that the hard metal plate is attached to the main tool body.

A toggle block adjustment arrangement for a jaw crusher is provided.

A mantle for a gyratory or cone crusher that includes a frame having a bowl as a first crushing shell, and a crusher head including the mantle as a second crushing shell, wherein the mantle and bowl define a crushing gap between them. The mantle includes a central axis, a first end and a second end along the central axis, and an outer peripheral surface defined by a generatrix rotating around the central axis. The outer peripheral surface constituting a crushing surface of the mantle, and an outer diameter of the mantle being larger at the second end than at the first end. One or more grooves are formed in the crushing surface at the second end of the mantle, and one or more cavities for receiving wear resistant inserts are formed in the crushing surface. One or more wear resistant inserts are bonded to or into the crushing surface.

A wear plate for a rotor for a comminution apparatus that is arrangeable adjacent to at least one of the wall elements and/or a further wear plate. The wear plate extends between an upper plate and a lower plate along a longitudinal direction. The wear plate includes a first body extending along a first general direction and has an upper surface, a lower surface, and a first abutment surface extending at least partially between the upper and lower surfaces. The wear plate includes a second body extending along a second general direction differing from the first general direction and has an upper surface, a lower surface, and a second abutment surface extending at least partially between the upper and lower surfaces. The wear plate is configured to abut a first surface and a second surface of the rotor such that, in use, forming a self-locking mechanism due to rotational force.

A wear-resistant body for crushing particulate material in the cement or mineral industries includes a body (1) provided with a plurality of highly wear-resistant inserts (3) embedded in complementary recesses (2) provided in the surface region (6) of the body. A ductile attachment part (4) is arranged within each recess (2), the ductile attachment part (4) being deformable by elastic or plastic deformation and the highly wear-resistant insert (3) being secured in the recess (2) by the ductile attachment part (4) after deformation. In some embodiments the ductile attachment part (4) is in the form of a ring or sleeve. A method for producing such a wear-resistant body is also provided.

An impact cutter blade and holder system is disclosed. The impact cutter blade and holder system includes: a cutter disk, a plurality of impact holders, and a plurality of impact cutter blades. The cutter disk has a central axis about which the cutter disk is configured to rotate. The plurality of impact holders are secured to the cutter disk. The plurality of impact cutter blades is secured to the plurality of impact holders.

A top wear plate for the rotor of a rock crusher, wherein the rotor includes a rotor body, the rotor body having an upper surface. The top plate includes a lip positioned about and descending vertically from the underside of the outer circumference of the lip wear plate, the lip including a protrusion to engage with a complementary recess on the top surface of the rotor body.

This disclosure relates to wear-resistant rubber compositions, such as those, for example, comprising at least one hydroxy-terminated polybutadiene, at least one natural rubber, at least one polymerization accelerant; at least one sulfur; and at least one polybutadiene, wherein the wear-resistant rubber composition may have an effective cross-linking density of at least about 3010.sup.5 moles/cm.sup.3.

A tooth shroud for a demolition tool is disclosed wherein forces produced during demolition operations may be dissipated so as to avoid excessive forces at stress points. A tooth block for a demolition tool comprises a first tooth shroud and a second tooth shroud. The first and second tooth shroud each comprising a body having a front wall and an end wall wherein a cavity is enclosed by the front wall and the end wall; an impact member extending longitudinally from the body; and a cut-out disposed on the end wall, wherein the first tooth shroud is connected to the second tooth shroud.

A mill including a mill body including a feeding pipe and a discharging pipe; a motor; and a vessel including a feeding port, a discharging port, and a supporting base. The vessel is disposed outside the mill body, and a sealing space is formed between the vessel and the mill body. The feeding port is disposed on the outer wall of the upper part of the vessel and is in a seal-tight connection with the feeding pipe of the mill body through a soft feeding joint, and the discharging port is disposed on the outer wall of the lower part of the vessel and is in seal-tight connection with the discharging pipe of the mill body through a soft discharging joint. The supporting base is disposed at the bottom of the vessel, and the mill body is installed on the supporting base via a cushion pad.
