Abstract
A gyratory crusher topshell and topshell assembly including an outer crushing shell and optional intermediate spacer ring. The topshell has a radially inward facing surface that is divided into a plurality of regions including an upper and lower mount region axially separated by an intermediate annular rib. The rib enables the topshell to be compatible with a variety of different sized and shaped concaves optionally using an intermediate spacer ring without the need for a backing compound.
Claims8
A gyratory crusher comprising:
- a topshell having an annular wall extending around a longitudinal axis of a frame part of the crusher, the wall being defined radially between a radially outward facing surface and a radially inward facing surface relative to the axis;
- and
- a crushing shell positioned radially inward of the topshell wall, the crushing shell comprising:
- an annular main body mountable within a region of the topshell, the main body extending around the longitudinal axis;
- the main body having a mating surface being outward facing relative to the axis positioning opposed to at least a part of the topshell and a crushing surface being inward facing relative to the axis to contact material to be crushed, at least one wall defined by and extending radially between the mating 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 relative to the mating surface and in a direction around the axis, the contact region having a radially outward facing raised first contact surface for positioning opposed to the inward facing surface of the topshell;
- a raised second contact region positioned axially towards the second lower axial end and extending radially outward relative to the mating surface in a direction around the axis, the second contact region having a radially outward facing raised second contact surface for positioning opposed to the inward facing surface of the topshell;
- and
- an annular groove extending around the axis and recessed radially inward relative to the first and second contact regions to axially separate the first and second contact regions.
