摘要： A rotatable grading pick has a head portion, a shank portion extending rearwardly from the head portion, and a polygonal portion on the rotatable grading pick. At least a portion of the outer perimeter of the polygonal portion can be engaged by a tool so that the polygonal portion can be rotated, and the shank portion can be rotated to clear debris between the shank portion and a retainer placed around a part of the shank portion.

摘要： A rotatable tool has a tool body that is generally symmetrical about a longitudinal axis, an enlarged cutting head, and a rearwardly extending shank. The shank joins the enlarged cutting head at an annular flange. A compressible sleeve is fitted around the shank and a wear ring is around the shank at the forward end of the sleeve. A disc spring is positioned between the radial flange and the sleeve to remove axial play between the shank and the sleeve and to seal the parts so that hard particles cannot enter and interfere with rotation of the tool.

摘要： A durable, weld-on chrome carbide tooth is provided for roll crushers. The tooth includes a chrome carbide body that is vacuum brazed to a mild steel backing plate. An upper portion of the tooth is preferably cast from chrome carbide alloy having 25 percent high-chrome-molybdenum content and a Brinell Hardness Number of about 700. The mating surfaces of the chrome carbide body and the mild steel backing plate are surface ground, then brazed together in a heat-treating furnace that has been evacuated to a pressure of less than 1×10−3 Torr. The minor differences in thermal expansion coefficients of the chrome carbide body and the mild steel backing plate are absorbed in the brazed joint, thereby reducing the buildup of mechanical stresses at the boundary layer. The mild steel backing plate enables the tooth to be welded directly to the drum of a rotary crusher.

摘要： A cutting bit retention assembly (399) that includes a cutting bit holder (500), which receives a cutting bit (58) and has shank (504) that extends into a bore (418) in a support (400). The shank section (504) of the cutting bit holder (500) presents a surface (530) defined by a notch (528) that selectively cooperates with a retention pin (670). A transverse bore (430) in the support (400) carries the retention pin (670). The retention pin (670) is selectively movable to any one of several positions. One position is a non-retaining position wherein the retention pin (670) does not engage the notch surface (530). Another position is a retaining position in which the retention pin (670) engages the notch surface (530) to urge the cutting bit holder into the cutting bit holder bore (418). Still another position is an ejecting position in which the retention pin (670) engages the notch surface (530) to urge the cutting bit holder (500) out of the cutting bit holder bore (418).

摘要： A tool pick assembly is provided for insertion in a first bore having a first diameter. The tool pick assembly includes a tool pick having a shank with a diameter sized for receipt in a second bore having a second diameter, the second diameter being smaller than the first diameter, an adaptive sleeve retainer having a thickness for stably supporting the shank of the tool pick in the first bore, and a washer for compressing the adaptive sleeve retainer to aid insertion into the first bore. The adaptive sleeve retainer is configured to spring radially outward to retain the tool pick in the first bore. A push out force for pushing the tool pick out from the first bore is approximately ±10% of a push out force for pushing out from the first bore a tool pick having a shank with a diameter sized for receipt in the first bore.

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.
