ABSTRACT:
A materials grinder has a materials receiving hopper, an exit opening into a shrouded grinding chamber and a powered ram for driving materials accumulated in the hopper to and through the exit into the grinding chamber. A grinding drum is rotatably disposed inside of a shroud adjacent the exit of the hopper to grind the ends of materials to be ground as they enter the grinding chamber and to continue to grinding as the materials are carried downwardly toward the bottom rear of the grinding chamber. The bottom of the shroud is open to receive an adjustable transverse shear bar assembly that is pivotally mounted to provide adjustment of the upper edges of the transverse shear bars with respect to the materials grinder drum.
