A crusher has a crusher head that is gyrated relative to a crusher bowl. The crusher head supports an annular mantle held by a mantle washer and a clamping plate clamped to a self-tightening nut by a clamping plate bolted to the nut. The washer covers a drained chamber in the crusher head and has drain holes for water from an annular recess formed by the inner edge of the mantle and the washer. A distributor plate having pickets covers the clamping plate and is positioned below a center distributing hopper in a larger hopper having a lining outwardly set back from an inwardly extending protective flange of a bowl liner. Self-locking pins lock eyebolts to the bowl liner and the eyebolts secure the bowl liner to a clamp bar through self-aligning washers. The clamp bar is bolted by fluted bolts to a bonnet secured to a bonnet support by holddown cylinders. A skirt on the crusher head overhangs a cam and thrust bearing structure mounting the cam and the crusher head. |
