Spider wall shield

A gyratory crusher spider protection assembly comprising:

• a plurality of wall shields arranged to be releasably mounted over an inward face of a spider positioned on a top shell of a gyratory crusher, each wall shield including a spider protection wall arranged to be positioned over the inward face of the spider, a rear wall extending upwardly from and projecting transverse to the protection wall, the rear wall having an inner face orientated radially inwards and an outer face orientated radially outward, the rear wall representing a radially outermost part of the wall shield, and at least one attachment element provided at the rear wall to attach the wall shield to the outer face;
• a fixating ring arranged to be positioned on top of and at the perimeter of the spider to extend circumferentially around at least part of the spider and the wall shields, the at least one attachment element attaching the wall shield to the fixating ring via the outer face;
• and
• a plurality of fixation elements securable respectively to each of the attachment elements to releasably fix the wall shields to the fixating ring such that the wall shields and the fixating ring are configured to form a unitary assembly.

A gyratory crusher comprising:

• a spider having a central hub and a plurality of spider arms extending radially outward from the hub towards an outer perimeter of the spider;
• a material feed hopper mounted axially above the spider;
• and
• a spider protection assembly including a plurality of wall shields arranged to be releasably mounted over an inward face of a spider positioned on a top shell of a gyratory crusher, each wall shield including a spider protection wall arranged to be positioned over the inward face of the spider, a rear wall extending upwardly from and projecting transverse to the protection wall, the rear wall having an inner face orientated radially inwards and an outer face orientated radially outward, the rear wall representing a radially outermost part of the wall shield, and at least one attachment element provided at the rear wall to attach the wall shield the outer face, and a fixating ring arranged to be positioned on top of and at the perimeter of the spider to extend circumferentially around at least part of the spider and the wall shields, the at least one attachment element attaching the wall shield to the fixating ring via the outer face, and a plurality of fixation elements securable respectively to each of the attachment elements to releasably fix the wall shields to the fixating ring such that the wall shields and the fixating ring are configured to form a unitary assembly, wherein the fixating ring is positioned axially intermediate the spider and the hopper.
