ABSTRACT:
Pellet molding apparatus for molding pellets from a powder material which includes a rotary index table upon which are placed a plurality of hollow cylindrical mold members spaced at equal radial and arc distances one from another. A mold filling station assembly is provided to fill the molds and a vertically operating hydraulic press at a pressing station compresses the powder in the cylindrical molds into pellets. A pivoted mold bottom operates upon a cam surface to maintain the bottom ends of the molds closed through the filling and pressing stations and swings open at an ejection station. An ejection station is provided and includes rams operating through the top of the mold member to force the compressed pellet out of the mold member through the open bottom end of the mold member.
