摘要： A block and non-rotating wear sleeve for holding a cutting tool used with mining and construction is disclosed. A key is used to intersect with notches in the wear sleeve and block at a rear face of the wear sleeve and block to prevent rotational movement between the wear sleeve and block. Locating the key and notches at the rear face provides an easily manufactured anti-rotation means which is also sheltered from the most of the abrasion experienced by the block and wear sleeve.

摘要： A wear component for use in an impact crusher having a forward depression on the face of the wear component which is exposed to aggregate wear. Wear resistant inserts, for example cemented tungsten carbide inserts, are bonded within the forward depression to prevent rapid abrasion of the wear component. Joints are formed between wear resistant inserts and joints are also formed between wear resistant inserts and the wear component. Bonding material fills the joints to further secure the wear resistant inserts and to prevent crack propagation.

摘要： A rotatable cutting tool that is useful for impingement upon a substrate and is adapted to be rotatably retained within the bore of a holder. The rotatable cutting tool includes an elongate cutting tool body, which has an axial forward end and an axial rearward end, as well as a socket at the axial forward end thereof. The rotatable cutting tool also includes a hard cutting member that is affixed to the cutting tool body within the socket. The hard cutting member has an axial forward end and an axial rearward end. The hard cutting member has a superhard axial forward portion at the axial forward end thereof wherein the superhard axial forward portion has a maximum transverse dimension. The hard cutting member further has a hard axial rearward portion contiguous with and axial rearward of the superhard axial forward portion. The hard axial rearward portion has a maximum transverse dimension. The ratio of the maximum transverse dimension of the superhard axial forward portion to the maximum transverse dimension of the hard axial rearward portion ranges between about 0.35 and about 0.45.
