Mixing and pelletizing machine

摘要

A mixing and pelletizing chamber includes a semicylindrical flexible trough of rubber or other material in which a rotor assembly mixes and pelletizes material moved from an inlet end to an outlet end. Springs are attached to the trough to resist movement of the trough in the direction of the rotation of the rotor assembly. The rotor assembly includes an axial shaft having transversely extending arms with blades at their outer ends with every fourth arm and blade being in a common plane. The blades are symmetrical and have converging flat surface to control product retention time in the pelletizer and are adjustably connected to the arms for providing adjustment of the force of the conveying action to the material in the trough. Adjustment is provided by aligned slots on opposite sides of the tubular arms receiving bolts on which the blades are carried. Optionally, the blade may nest in a semicylindrical portion of the tubular arm for angular adjustment.
