ABSTRACT:
Tooth assemblies upon the breaker rings of the rotor of the apparatus each include tooth and seat components having abutting surfaces that prevent forward, rearward, inward and lateral movement of the tooth relative to the seat and rotor. Outward tooth movement during operation of the apparatus is prevented by a pin that extends generally parallel to the rotor axis through aligned bores within the tooth and its seat. The pin is shielded from damaging impacts with the material being ground and from detrimental bending stresses, and is releasably retained within the bores by a detent that permits convenient removal of the pin when replacement or repair of the tooth is required.
