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.
Claims5
A hammer mill for crushing materials, comprising:
- a cylindrical case clad with armor plates on its inside,
- a rotor journalled on the case and carrying a plurality of hammers, and
- anchor means for holding each hammer on the rotor at a position to confront the armor plates, said anchor means comprising a mortise formed at the rotor periphery and having opposed walls arranged to converge outwardly in a dovetail-like manner, the opposed walls of the mortise forming an angle therebetween within the range of 5.degree. to 20.degree.,
- the hammer including an integrally-formed tenon having a cross-sectional shape matching that of the mortise and engaging with the walls thereof, the tenon being urged to wedge itself in a stable fashion between said mortise walls by centrifugal force applied to the hammer by the rotating rotor.
