Abstract
A comminuting striker and retainer for mounting to a striker mounting face of a comminuting rotor by bolts in which the striker is located by a projection on the retainer which can be disengaged from the striker by loosening the bolts without removing the bolts and retainer from the rotor, the striker having a slot which then allows the striker to be slid laterally from the bolts for removal from the rotor.
Claims9
A comminuting striker for mounting on a rotor of a comminuting apparatus, comprising a body having opposed first and second ends, the first end of which defines a cutting edge and the second end of which defines a slot extending toward the first end, the slot being sized to provide passage for bolts used to attach the striker to a striker mounting face of the rotor and being shaped to allow the striker to be removed from the rotor without removing the bolts from the rotor, wherein the slot is an elongate slot having parallel walls in which are formed opposite recesses able to accommodate a projection used to retain the striker on the rotor.
A method facilitating replacement of a striker of a comminuting rotor in which the striker is clamped to a mounting face of the rotor by bolts, when tight, in engagement with the rotor and a retainer with the striker held in place by a projection on the retainer engaging a cooperating opening in the striker, comprising the step of:
- a) providing a slot in the striker to permit movement of the striker laterally of the bolts;
- b) loosening the bolts sufficiently, without the removal of the bolts and retainer from the rotor, to permit the projection to disengage from the opening;
- and
- c) sliding the slot of the striker laterally from the bolts to remove the striker from the rotor.
