Abstract

The rotor of the crusher receives the stones at its centre. It comprises three blades (20, 21) which, except on the ejecting edges (22), are protected against internal wear by their hollow shape which retains a protective layer of stones. These edges are protected from impacts by protecting plates (24) arranged radially in front of them. <IMAGE>
