The crusher includes: a housing defining a crushing chamber; at least one elevation adjustable impact barrier mounted in the crushing chamber; a barrier adjustment mechanism configured to adjust an elevation of the at least one impact barrier within the crushing chamber; and a rotor mounted in the crushing chamber and turned by a drive mechanism. The rotor is configured to direct feed material toward the at least one impact barrier. The bather adjustment mechanism includes at least one hydraulic cylinder mounted to the at least one impact barrier. The cylinder includes a sensor for detecting an absolute extension of the cylinder. A system for crushing a crushable material including an impact crusher and controller is also provided herein.

Abstract: Apparatus and methods for mechanically cleaving a bonded wafer structure are disclosed. The apparatus and methods involve clamps that grip the bonded wafer structure and are actuated to cause the bonded structure to cleave.

Abstract: A crusher is provided having improved wear resistance and crushing capacity. Particularly, the crusher provides an improved mechanism for adjusting the closed side setting by acting on an adjustable jaw, rather than the moveable jaw. The crusher includes a moveable jaw, an adjustable jaw, and a frame that supports the adjustable jaw and the moveable jaw such that the adjustable jaw and the moveable jaw define a crushing chamber having an upper opening for receiving a material to be crushed and a lower opening for expelling crushed material from the chamber after crushing. The crusher also includes a drive mechanism coupled to the moveable jaw for directing reciprocating motion of the moveable jaw and an adjustment mechanism coupled to the adjustable jaw for altering an angle of the adjustable jaw and, thereby, altering a closed side setting of the crushing chamber.

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: A method and apparatus for adapting a horizontal shaft impact crusher for efficient crushing of different types of material are provided. At least two feed plates are provided. The feed plates each have a different feed angle adapted for use with a predetermined type or types of aggregate material. The feed plates can be interchangeably mounted on the crusher to adapt the crusher for enhanced crushing efficiency with respect to the type of material to be crushed.

Abstract: An improved vertical shaft impact crusher, and in particular a crusher having a shoe assembly attached to a rotatable table assembly, the shoe assembly comprising a bracket, a shoe, and mounting bolts for removably attaching the shoe to the bracket. The shoe has a contact surface which engages a support surface of the bracket to reduce shear forces in the mounting bolts during rotation of the table assembly. The crusher also has a liner for protecting an outside face of the bracket. The liner has spacers located on a mounting surface which create a gap between the liner and the bracket, thereby reducing a prying action caused by uneven deflections in the mounting bracket during rotation of the table assembly.

Abstract: An apparatus for selectively relieving the load on the adjusting rods of a horizontal shaft impact crusher is disclosed. The apparatus includes a linear actuator mounted to the exterior of the crusher frame. It also includes a bridge having a bearing section disposed adjacent the linear actuator. The bridge is secured to the adjusting rods such that, energizing the linear actuator applies a force to the bearing section of the bridge to thereby at least partially relieve the load on the adjusting rods. The bridge is sized such that, when the linear actuator is in the released state, the bridge does not add to the height of the crusher.

Abstract: An apparatus is disclosed for controlling the movement of the adjusting rods of a horizontal shaft impact crusher when the crusher is opened for service or the like. The disclosed apparatus includes a guide mounted to the crusher and defining a cavity. The cavity receives an adjusting rod and is dimensioned to force the adjusting rod to pivot in a predetermined direction when the crusher is opened.

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.
