A torque reaction pulley for an inertia cone crusher having an elastically deformable component responsive to a change in torque through the drive transmission of the crusher due to rotation of an unbalanced weight within the crusher.

Torque reaction pulley for an inertia cone crusher

A gyratory crusher bottomshell and inspection hatch assembly is attachable exclusively to the bottomshell via a wear plate positioned at an internal region of the bottomshell. A wall thickness of the bottomshell at a border region immediately surrounding the hatch opening is generally equal to or less than a wall thickness over a remainder region of the wall at the same axial height position of the hatch opening.

A gyratory crusher topshell having an annular shell wall that is strengthened to minimize stress concentrations and increase the topshell operational lifetime. The topshell includes spider arms that are structurally reinforced at their radially inner regions and also has an annular wall that is reinforced at regions immediately below the spider arms to further increase strength and facilitate casting.

Gyratory crusher topshell

A drive mechanism for an inertia cone crusher having a drive transmission to rotate an unbalanced mass body within the crusher and to cause a crusher head to rotate about a gyration axis at a tilt angle formed by an axis of the crusher head relative to the gyration axis. A torque reaction coupling is positioned in the drive transmission between the mass body and a drive input component and is elastically displaceable and/or deformable. In particular, the torque reaction coupling is configured to: i) transmit a torque from the drive input to the mass body and ii) to dynamically displace and/or deform elastically in response to a change in the torque resultant from a change in the tilt angle of the crusher head so as to dissipate the change in the torque to the drive transmission.
