Copper crusher gauge holder

A copper crusher gauge holder for testing internal pressures of cartridges during test firing is provided. The copper crusher gauge holder has a circular aluminum upper plate and a circular aluminum lower plate having a layer of urethane rubber approximately 3/4 inch thick sandwiched between the plates. The gauge holder is bored to hold copper crusher gauges and center-bored to fit over a cartridge centerline primer tube. A series of machine screws hold the plates together and allow for tightening the screws once the copper crusher gauge holder is in place in a cartridge to be tested. As the machine screws are tightened, the urethane rubber expands laterally gripping the inside of the cartridge and gripping the copper crusher gauges. A method to manufacture the gauge holder is provided.

Impeller mounting system for centrifugal impact crusher

A system for mounting material directing impellers to the table of a centrifugal impact crusher includes an upstanding mounting plate having a slot extending through it which opens out of its top surface. An impeller has a rearwardly facing stob extending from it which slidably fits within the slot. A nub, which does not fit through the slot, is attached to the extremity of the stob and the stob is sized such that the nub and the rear surface of the impeller interact with the mounting plate to prevent the impeller from moving relative to the mounting plate in either circumferential direction. The sides of the slot are angled radially outwardly as they extend downwardly toward the table.

Device for securing the stationary jaw of a jaw crusher

A device for securing the stationary jaw to the frame of a jaw crusher is disclosed. The device includes a crusher frame having top and bottom spaced apart cross members, a stationary jaw, and a threaded draw rod having a pair of inwardly moveable wedge members. The stationary jaw includes a top edge, a bottom edge, and a pair of interconnecting sides, and further includes a top lug adjacent the top edge and a bottom lug adjacent the bottom edge. The top lug is adapted for placement adjacent the frame top cross member, and the bottom lug is adapted for placement adjacent the frame bottom cross member. The draw rod is disposed such that the wedge members are positioned to engage the jaw top lug and the frame top cross member. Accordingly, in response to inward movement of the wedge members, the stationary jaw is progressively more firmly secured to the frame, thereby preventing undesired movement of the stationary jaw during operation of the crusher.

Shoe mounting bracket for a vertical shaft impact crusher and liner for same

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.
