Abstract:
PCT No. PCT/AU95/00490 Sec. 371 Date Feb. 11, 1997 Sec. 102(e) Date Feb. 11, 1997 PCT Filed Aug. 11, 1995 PCT Pub. No. WO96/04994 PCT Pub. Date Feb. 22, 1996The gyratory crushing apparatus includes a bowl having an inner wall which defines a chamber for receiving frangible or friable material to be crushed, the chamber having a central axis and terminating in a throat defining a central discharge opening, a crushing head disposed in the bowl and having upper and lower ends which are interconnected by a peripheral wall which is concentric with respect to a gyratory axis of the head, a support assembly by which the head is supported in the chamber and which includes a shaft, and a drive arrangement coupled to the shaft. The shaft is of integral construction having upper and lower portions, and the head is mounted on the upper portion, with the upper portion having an axis substantially co-incident with the gyratory axis of the head. The lower portion of the shaft has an axis which is substantially co-incident with the central axis of the bowl, with the axes of the upper and lower portions of the shaft intersecting at a fixed point located proximate to, or co-incident with, the lower end of the head. With rotation of the shaft about the axis of its lower portion under the action of the drive arrangement, gyratory motion is imparted to the head to provide a crushing action between the bowl and peripheral wall of the head, on material received in the chamber.
