GYRATORY CRUSHER OUTER CRUSHING SHELL AND SEALING RING ASSEMBLY

摘要

A gyratory crusher outer crushing shell and a crushing shell assembly. The crushing shell includes a radially inward facing crushing surface and a radially outward facing mount surface provided with radially outward projecting contact regions to contact the topshell or an intermediate spacer ring. A ledge or groove providing an abutment face is positioned at or axially above the upper contact region to positionally support a sealing ring for positioning between the crushing shell and the topshell or intermediate spacer ring.

主权项

1. A gyratory crusher outer crushing shell mountable within a region of a topshell of a gyratory crusher and extending around a longitudinal axis, the crushing shell comprising:
a mount face being outward facing relative to the axis for positioning opposed to a least a part of the topshell and a crushing face being inward facing relative to the axis to contact material to be crushed, a wall defined by and extending radially between the mount surface and the crushing surface, the wall having a first upper axial end and a second lower axial end; a raised first contact region positioned axially towards the first upper axial end and extending radially outward at the mount surface and in a direction around the axis, the raised first contact region having a radially outward facing raised first contact surface for positioning opposed to a radially inward facing surface of the topshell or an intermediate spacer ring; a raised second contact region positioned axially towards the second lower axial end and extending radially outward at the mount surface in a direction around the axis, the raised second contact region having a radially outward facing raised second contact surface for positioning opposed to a radially inward facing surface of the topshell; and an abutment face to seat a sealing ring positionable between the mount surface and the topshell or spacer ring, a radial length of the abutment face being less than a radial thickness of the wall at the region between the first upper axial end and the raised first contact region, the abutment face being provided by and selected from a ledge or groove provided at the mount face side of the wall at a position of the raised first contact region or axially between the first upper axial end and the raised first contact region.
