Embodiment Construction

[0024] refer to figure 1 The gyratory crusher sump 100 includes a sump wall 101 extending circumferentially around a central longitudinal axis 115 . The wall 101 comprises an axially uppermost annular end 111 and a lowermost annular end 112 . In particular, annular rim 102 projects radially outwardly from wall 101 at upper end 111 to provide a flange for coupling to a top case frame (not shown). The central hub 107 extends circumferentially around an axis 115 and is positioned radially inwardly of the housing wall 101 towards the axially lowermost end 112 . The hub 107 is supported and held in place within the housing wall 101 via a plurality of support arms 106 extending radially between a radially outermost region 110 of the hub 107 and the radially inwardly facing surface 103 of the housing wall 101 middle.

[0025] Hub 107 includes a central cavity 114 axially aligned with respect to axis 115 to receive a gyratory crusher main shaft (not shown) and support the shaft tow...

Abstract

A gyratory crusher bottom shell and bottom shell assembly in which protective liners are mounted over and about respective support arms (106) that extend radially between the bottom shell wall and a central hub (107). The support arms (106) comprise a seat or saddle region with at least a part of the liner positioned in contact with and supported by the seat to distribute the mass of the liner radially between the hub (107) and the shell wall and to reduce tension in the primary attachment bolts.

Description

technical field [0001] The present invention relates to a gyratory crusher sump and a sump assembly wherein support arms extending radially to mount the central hub of the sump are shaped and / or configured to provide seats to at least partially accommodate each Arm pads to provide a safe and effective means of mounting the pads at the bottom case. Background technique [0002] Gyratory crushers are used to crush ore, mineral and rock materials into smaller sizes. Typically, a crusher includes a crushing head mounted on an elongated main shaft. The first crushing shell is mounted on the crushing head and the second crushing shell is mounted on the frame such that the first and second crushing shells together define a crushing chamber through which the material to be crushed passes. [0003] The rotary pendulum motion of the crushing head is supported by a lower bearing assembly positioned below the crushing head and a top bearing journaled with the upper end of the main sha...
