Abstract: A system and method for absorbing shock and reducing wear on a V seat of a cone crusher, where a plurality of sheets of brass, each having slots therein extending into the sheet from opposing sides, are bolted to a top portion of the V seat and made to conform so as to extend over an exterior portion of the V seat, a top portion of the V seat and an inside portion of the V seat, when the top of the cone crusher bends the sheets as the top of the cone crusher is moved closer to the V seat.

Abstract: A gyratory cone crusher with a conehead centerline and a main centerline being skewed and non-coplanar with respect to each other. The conehead exhibits an elliptical movement path which results in faster throughput and enhanced cubicity performance.

Abstract: A retaining wedge assembly for securing an impeller bar to the rotor of a horizontal shaft impact crusher comprises a recess defined in the rotor and sized to receive the impeller bar. The recess includes a first seat shaped to engage a first portion of the impeller bar and a second seat. A retaining wedge includes a first portion adapted to engage a second portion of the impeller bar, and a second portion sized to engage the second seat. A countersunk slot on the second seat receives the retaining wedge, which in turn cooperates to secure the impeller bar in the recess. Guide flanges may be provided for limiting axial movement of the retaining wedge. Thus, the impeller bar may be supported in the recess prior to start-up of the horizontal shaft impact crusher.

Abstract: A horizontal shaft impact rock crusher having breaker plates which are adjustable by hand, using a novel tension rod adjustment nut locking device which employs several loose-fitting retaining devices which, in combination with a bridge to a frame member or another tension rod, hold the tension rod adjustment nut in place.

Abstract: A horizontal shaft impact rock crusher having breaker plates which are coupled to a shaft or pins which rest in voids along an edge of the crusher and are held in place by a retainer device, such that the breaker plates with the shaft or pins still attached can be removed from the crusher by releasing the retainer devices.

Abstract: On a vertical shaft impact crusher, a table assembly having a reinforcing ring is disclosed. The vertical shaft impact crusher for crushing aggregate material includes a frame, with the table assembly being mountable to the frame for rotation about a vertical axis. The crusher includes a housing defining an impact surface spaced about an interior of the housing and surrounding the table assembly. The table assembly comprises a top surface, a bottom surface, and a peripheral edge. The top surface includes a central portion defining an aggregate landing surface, with the central portion being adapted to permit outward migration of the aggregate material in response to rotation of the table assembly. A plurality of shoe assemblies are mounted to the top surface adjacent to and spaced along the peripheral edge, with each shoe assembly being adapted to cause the outwardly migrating aggregate material to be thrown against the housing impact surface in response to rotation of the table assembly.
