ABSTRACT:
In a gyratory crusher the crusher head is mounted on a drive shaft which is driven by an eccentric. The eccentric is continually rotated to cause the head to gyrate for effecting the crushing of material. an antispin arrangement is provided to prevent rotation of the crusher head in the same direction as the eccentric under idling conditions or no load conditions. The antispin device includes a pair of ratchets one of which is coupled to the shaft and the other of which is formed on the end face of a piston which is held in the counterbore of the drive shaft by a spring. A rectangular torsion rod extends through the center of the piston into a clearance hole bored in the crusher head drive shaft. The top of the torsion rod is anchored in the spider cap of the crusher.
