Description: |
| Abstract:
This invention relates to that class of stone- breakers and ore-crushers which have a flaring hopper or conical concave and all upright shaft carrying a conical crusher-head near its upper or fulcrum end, said shaft and crusher being gyrated and revolved by means of a revolving eccentric, to which the shaft is connected loosely by its lower end, motion being imparted to the eccentric by gearing, one wheel of which is rigidly fastened to it below the crusher-bead and concave, and isolated by a dust-collar and an inclined diaphragm or laterally discharging partition of the frame of the stone-breaker.
Claim:
The combination of a gyratory shaft provided with main and auxiliary crushing-surfaces and a hopper provided with reversely-tapered crushing-surfaces, the respective sets of opposing crushing-surfaces being together adapted for breaking stone or other substances into fine pieces, while the lower of said sets is adapted to be moved entirely out of operative relation, and the upper set to be used alone for breaking the stone or other substances into coarser pieces. |
