Gyratory crusher including a variable speed drive and control system
A system and method for controlling the operation of a gyratory rock crusher is shown and described. The gyratory rock crusher includes a variable frequency drive that allows the eccentric speed of the gyratory crusher to be modified based upon sensed parameters of the rock crushing system. The speed of the eccentric rotation can be dynamically adjusted to compensate for the size of the material particles being crushed and the availability of the material. The use of the variable frequency drive increases the operating efficiency of the gyratory crusher by controlling the discharge flow rate of the crushed material from the crusher and thus allows for a reduction in the size of the discharge hopper. The rotational speed of the eccentric is controlled to be below the critical speed for the gyratory crusher.
A screw shaft for a vertically stirred grinding mill is arranged so as to be accommodated within a grinding chamber of the grinding mill while extending in a longitudinal direction.

A counterweight for use in a cone crusher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crusher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wall 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 wall 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 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 grinding assembly for the comminution of material that enhances the durability of the side edges of both a grinding roll and a flange roll. Both the grinding roll and the flange roll include a wear ring that is received within a side groove formed at each end of a cylindrical roll body. The wear ring includes a series of spaced receiving cavities that each receive a wear member. Each wear member includes a radially outer surface and an axial end face to enhance the durability of the edge of the roll body. The edge ring is retained on the roll body by a series of connectors that pass through the edge ring. In the flange roll design, a flange ring is attached to the roll body by a series of connectors that also secure the edge ring to the roll body.
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.
A cone crusher includes a stationary main shaft and an eccentric that rotates about the main shaft to cause gyrational movement of a head assembly to crush rock within a crushing gap. The cone crusher includes a counterweight assembly mounted for rotation with the eccentric. The counterweight assembly includes a counterweight body having a series of tanks. Each tank can receive either a first ballast and a second ballast or a combination thereof. The first ballast is formed from a material having higher density than the second ballast to increase the concentration of weighting in desired locations around the counterweight assembly.
