A bale shredder may comprise a bale hopper defining an interior bale chamber for receiving a bale to be shredded, a bale shredding assembly to shred a bale in the chamber including a shredding rotor having a plurality of flails to contact a bale in the bale chamber, and a passage for receiving material shredded by the shredding rotor. In embodiments, a conveying assembly may facilitate material flow through the passage with a moving conveying surface. A collecting auger assembly may collect material ejected by the shredding rotor through the passage and may include an auger with an auger shaft rotatable about a rotation axis. In embodiments, a discharge assembly with a discharge rotor configured to receive the shredded material from the collecting auger assembly and expel the material through a discharge opening, and the discharge rotor may rotate on the auger shaft of the collecting auger assembly.
