Abstract:
A gyratory crusher includes an inner and an outer crushing shell. The outer crushing shell has three regions along its axial length including: an inlet region that tapers radially inward from an uppermost first end; a crushing region that extends radially inward from a second lowermost end; and a radially innermost shoulder region that is positioned axially between the inlet and crushing regions. An angle of inclination of a radially inward facing surface at the inlet and shoulder regions and the axial length of the crushing surface are designed to optimise crushing capacity in addition maximising reduction.

Claim (Index 1):
A gyratory crusher outer crushing shell comprising:\n a main body arranged to be fixedly mounted to a topshell frame of a gyratory crusher, the main body extending around a central longitudinal axis; the main body having an inlet region having a mount surface being outward facing relative to the axis for positioning against at least a part of the topshell frame and a contact surface being inward facing relative to the axis to contact material to be crushed, at least one wall of the main body being defined by and extending between the inlet region mount surface and the inlet region contact surface, the wall having a first axial end and a second axial end, an orientation of the inlet region contact surface extending from the first axial end being inclined so as to project radially inward towards the axis in an axially downward direction to define the inlet region; an axially lowermost part of the inlet region terminated by a single shoulder region, the shoulder region having a contact surface being inclined so as to project radially inward towards the axis from the inlet region contact surface in an axially downward direction, wherein an angle of inclination of the inlet region contact surface relative to the axis is less than an angle of inclination of the shoulder region contact surface relative to the axis, wherein the single shoulder region terminates at the inlet region; and a crushing region having a crushing region contact surface extending from an axially lowermost part of the shoulder region to the second axial end, the crushing region defining a crushing face that extends immediately from the axially lowermost part of the shoulder region contact surface, the crushing face being orientated to decline and to project radially outward relative to the axis in a downward direction from the shoulder region to the second axial end, a wall thickness of the main body being approximately uniform along an axial length of the crushing region, wherein when associated with an inner crushing shell of the gyratory crusher a majority of the outer crushing shell contact surface is substantially parallel with an outer surface of the inner crushing shell.
