Abstract

A rotary pelletizing machine includes a housing and a pelletizing assembly removably secured in the housing and including a rotatable matrix disc, upper and lower punches supported in the matrix disc for joint rotation therewith and axial displacement relative thereto, upper and lower cams for controlling positions of the upper and lower discs, and elements that enable rotation of the matrix disc relative to the cams. Upon releasing elements that secure the assembly in the housing, the pelletizing assembly can be lifted from a drive shaft that extends in the housing for imparting rotation to the matrix disc, as a unit.
