ABSTRACT:
A mill for crushing tree trunks is disclosed which includes a rotor having a series of crushing blades disposed helically around the rotor. The rotor blades pass between axially spaced stator blades in the mill housing to crush the trunks and liberated associated foreign matter. The crushed material and liberated foreign matter is moved toward one end of the mill housing by the action of the helically disposed rotor blades where it is discharged from the mill.
