COLLISION MEMBER WITH COLLISION SURFACE RELIEF

摘要

The method and the device according to the invention relates to a stator and an armoured ring which are combined to give a stationary annular collision member that is arranged around the rotor, as it were in the form of a stator that is provided all round along the inside, which faces the axis of rotation, with protruding collision surface reliefs, each of which is provided with at least one collision surface that is arranged transversely in the ejection stream that the material describes when it is propelled outwards from the rotor.
