    摘要: A drill steel-chuck assembly which includes a drill steel which has a plurality of faces and opposite ends. The drill steel has one portion adjacent one of the opposite ends thereof and a mediate portion spaced apart from the one portion. The drill steel further has one transition portion between the one portion and the mediate portion so as to join the one portion and the mediate portion. The one portion of the drill steel presents a first orientation of the faces. The mediate portion of the drill steel presents a second orientation of the faces. The one transition portion of the drill steel presents a twisted orientation of the faces comprising a generally constant twist of the faces from the first orientation of the one portion to the second orientation of the mediate portion. There is a chuck for attachment to the drill steel through engagement with the transition portion of the drill steel.

    摘要: An impact crusher includes a center feed disk. The center feed disk includes a peripheral edge portion, a first face, an opposing, second face, a central bore extending through the first and second faces, and first and second countersunk pockets provided about the central bore in the first and second faces respectively. With this arrangement, a fastener having a shaft portion and a head portion can be inserted through the central bore to secure the center feed disk to a drive mechanism, with the head portion residing in the countersunk pocket. With this arrangement, once the first face portion becomes worn, the center feed disk can be removed, inverted and re-mounted such that the second face portion is exposed.

    摘要: A pivot pipe for a two-cylinder thick material sludge pump is designed to reduce the rate of wear of the sealing surfaces and flow bores of the pivot pipe and cooperating outlets on the two pump cylinders. As the pivot pipe oscillates from one pump cylinder to the other pump cylinder the contacting sealing surfaces are subjected to abrasion and impact wear. The present invention limits the rate of wear between the contacting sealing surfaces and a portion of the flow bore by fixing monolithic wearing rings on the upstream end of the pivot pipe and on the outlets of the two pump cylinders. The monolithic wearing rings are made of a hard materials such as cemented tungsten carbide.

    摘要: The present invention is particularly, but not exclusively, useful for reducing wear of component parts of impact-type rock-crushing machines caused by earth aggregate flows during operation of impact crushers. The present invention includes a central feed body and impeller shoe that has hard material insert bars fixed therein to reduce wear. The exposed top surface of the central feed body and front face of the impeller shoe are impregnated with a plurality of cemented carbide insert bars. The cemented carbide insert bars form an upper composite matrix that helps to reduce wear and the premature wash out of the hard material insert bars integrally cast within the central feed body.
