A counterweight for use in a cone crasher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crasher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wail and splash shield define an inner oil chamber while an outer oil chamber is defined by the splash shield, the vertical separating wall and an inner wail of the counterweight. Both the inner and outer oil chambers include drain holes that allow lubricating oil to pass through a generally horizontal floor of the counterweight. The combination of the inner and outer oil chambers allows oil to quickly exit the counterweight into the main oil sump and reduces the amount of oil that gets exposed to the upper seal assembly which reduces the passage of oil past seal assemblies formed in the cone crusher.

A system and method for providing the required clamping force between an adjustment ring and bowl of a gyratory crusher is disclosed. The clamp ring includes a series of clamping cylinder assemblies that each are mounted to a top face of the clamp ring. Each of the clamping cylinder assemblies can be removed and replaced from the top surface of the clamp ring without requiring the removal of the clamp ring from the gyratory crusher. Each clamping cylinder assembly includes a mounting flange that is attached to the clamp ring through a series of connectors.

A hydraulic separation system for use in a gyrational crusher to separate a socket of the crusher from a main shaft. The hydraulic separation system includes one or more hydraulic grooves formed at the interference contact area between the socket and the main shaft. Each hydraulic groove is fed with a supply of pressurized hydraulic fluid to aid in separation of the socket from the main shaft. An inner contact surface of the socket is tapered and engages a tapered outer surface of the main shaft. The mating tapered surfaces further aid in separation of the socket from the main shaft upon application of the pressurized hydraulic fluid.

An adjustment and suspension system for supporting the mainshaft of a gyratory crusher within a stationary spider hub. The system includes a piston movable within the spider hub to adjust the vertical position of the mainshaft. A stop member positioned within the spider hub controls the maximum vertical movement of the piston within the spider hub. A drive assembly is used to adjust the vertical position of the stop member to limit the vertical position of the mainshaft. The mainshaft is supported by a vertical support bearing and a radial support bearing that are located separate from each other. The vertical position of the drive shaft is controlled by a supply of pressurized hydraulic fluid introduced into the spider hub to control the vertical position of the movable piston.

A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.
