ABSTRACT:
In a material smashing machine, such as a breaking or crushing machine, a housing is provided with at least a portion of its wall lined by a stationary wearing wall against which, in use, the material to be broken or crushed is beaten, ground, or otherwise smashed. The wearing wall is formed, at least in part, by a number of replaceable wearing plates each of which has, on its face adjacent the housing wall, at least one cranked finger which penetrates through a slot in the housing wall and engages with its cranked end the outside of the housing wall to hold the wearing plate against the housing wall. The stability of this fixing can be increased by providing the facing end surfaces of adjacent wearing plates with inter-engaging means including at least one projection on one end surface fitting into a corresponding recess or recesses in the other end surface.
