Abstract
In an impact crusher for reducing the size of particulate material, the breaker bars having one or more quasi-circular depressions for engaging a circular back-up bar is secured to a rotor by means of a serrated wedge and C-clamp assembly. A newly designed housing opening permits the breaker bars to be placed in an optimum horizontal positioning and a rotor-locking assembly holds the back-up bars in this optimum positioning and provides support for the breaker bars during replacement thereof.
