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.


The invention relates to an energy harvester for converting vibrational motion of a vibrating equipment into electrical energy. The energy harvester comprises a pendulum arranged to be pivotably attached to said vibrating equipment, a motion limiter arranged to limit a pivoting motion of said pendulum, and a generator connected to said pendulum and arranged to convert said pivoting motion into electrical energy. The vibrational motion has an operating frequency, and said pendulum has a natural frequency different from said operating frequency. The invention also relates to a device for monitoring the operation of a vibrating equipment.

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.

The present invention relates to a roller crusher (1) having a base frame (11) and a roller frame (6) movably connected to said base frame (11). Two generally parallel rotatable rollers (7, 8) separated from each other by a gap are arranged in said roller frame (6). The roller crusher (1) further comprises a feeding arrangement (2) mounted to the base frame (11) for feeding material to the rollers (7, 8) and at least one balancing cylinder (17, 18) is provided which are connected to and arranged to manipulate the roller frame (6) relative to the base frame (11) such that the position of the rollers (7, 8) relative to the feeding arrangement (2) can be adjusted. Front and rear cheek plates (28) are provided at the roller frame (6) partially covering front and rear end surfaces of one of the rollers (7, 8) and at least partially covering an opening between the feeding arrangement (2) and the two rollers (7, 8), the cheek plates (28) being fixedly mounted to the roller frame (6).

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.

The present invention relates to a roller crusher (1) having two generally parallel rotatable rollers (7, 8) separated by a gap, and a feeding arrangement (2) for feeding material to the rollers (7, 8). The roller crusher (1) further comprising a base frame (11) and a first and a second roller frame section(9, 10), each of the first and second roller frames sections (9, 10) being pivotably connected to the base frame (11) and arranged for carrying one of the rollers (7, 8) in bearings arranged at opposed ends of each roller (7, 8). The roller crusher (1) also comprises at least one balancing cylinder (17, 18) extending between one of the roller frame sections (9, 10) and the base frame (11) such that when the at least one balancing cylinder (17, 18) is activated, the interconnected roller frame sections (9, 10) will pivot relative to the base frame (11), thus adjusting the position of the rollers (7, 8) relative to the base frame (11).
