ABSTRACT:
The gap between the bowl cone and the gyrating cone of a cone crusher, though adjustable by hydraulically lifting the bowl, is safely fixed during crushing by shims for vertical firmness and by a ring of wedge segments binding the side of the bowl. Both are held firm by spring washers, with no need to maintain a hydraulic pressure. For adjustment hydraulic jacks of one set release both shims and wedge, with the correct sequencing for removal of shims. A floater ring is normally pressed by one set of spring washers for clamping the shims. When it is pressed down hydraulically it first releases the shims, but further movement under influence of a small pump presses down the wedge segments, overcoming the spring washers which normally press the wedge segments for wedging. The shims are double shim plates some of which have slots that prevent removal of the right hand end until the left end has been swung free, and the others of which are just the opposite. Removal is dependably prevented by a pin through these shims. Oil jets at nearly the same height deliver oil to upper and lower bearings, with the upper jets jumping a gap of gyration, without need for overflooding the lower bearings, so that moderate total flow is sufficient for cooling all bearings. The pedestal spider arms, which support the inner base from the outer base while letting crushed rock fall to discharge between them, are made hollow and sealed by a bottom plate, thereby enlarging the reservoir, improving cooling, and providing fully protected tunnels from outside of the falling rock to the inner base for various selected uses.
