A material debagging apparatus includes a receptacle movable between upright loading and inverted dumping positions. The receptacle defines a bagged material holding chamber with a closed bottom and an open top. A rupturing mechanism in the form of a pair of generally parallel drums having circumferential rows of teeth thereon is carried on the receptacle adjacent the closed bottom of the chamber. The rupturing mechanism is operable for rupturing a bag at least partially filled with material and disposed in the chamber with the bottom of the bag overlying the rupturing mechanism. A drive mechanism is coupled to the drums of the rupturing mechanism for transmitting rotary power thereto to cause counterrotation of the drums. The rupturing mechanism includes a grate-like structure consisting of a plurality of laterally spaced bars disposed above the drums for supporting the bag while it is being ruptured. The spaced bars extend between the rows of teeth and serve to strip the ruptured bag from the teeth thereby preventing the ruptured bag from becoming wrapped around the drums.
