ABSTRACT:
A hammer mill for crushing ore and the like materials comprises a cylindrical case provided with armor plates on its inside, and a rotor journalled in the case and carrying a plurality of hammers, as well as anchor means for holding each hammer to the rotor at a position facing the armor plates, which includes a mortise, formed at the rotor periphery and having opposed walls convergent outwardly and substantially dovetail-like, and a tenon formed on the hammer integrally therewith and having a cross-sectional shape which matches that of the mortise, said tenon engaging with the mortise walls and being urged, by the centrifugal force developed within the hammer by the rotating rotor, to wedge itself stably in between said mortise walls.
