Abstract
A material smashing machine, such as a breaking or crushing machine, including a housing in which at least a portion of its wall is 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 by a number of replaceable wearing plates, each of which has at least one eyelet projecting outwards through an opening in the housing wall, and which is retained against the inside of the housing wall by a wedge inserted into the eyelet and bearing against the outside of the housing wall, and a releaseable, self-locking clamping piece acts upon the wedge in the direction of its insertion into the eyelet.
