ABSTRACT:
The invention relates to a device for fastening an armour to the crushing cone of a crusher having an armour-clad outside cone and an armour-clad crushing cone mounted therein on a spherical support. The device comprises a pressure bush and a screw provided with a flange threaded into a bore in the central area of the crushing cone. The pressure bush is arranged in the upper end face of the armour-clad crushing cone and it is provided with projections. The flange is provided with threaded bores and slots to receive the projections of the pressure bush. The pressure bush is located under the flange with a clearance there between and said clearance being fixed with distance bolts threaded into the threaded bores of the flange and bearing against the pressure bush, thereby generating an interference between the thread of said screw and the bore of the crushing cone.
