Abstract
An apparatus for removing dust-containing or hazardous material from bags includes a vertical bag feeding chute having one or more vertically disposed knife blades fixed (no moving mechanical parts) in the chute to slice open the bag as it falls through the chute. The sliced bag is caught in a downwardly angled perforated basket disposed below the bag feeding chute where an operator operating through a glove box removes solid material from the interior of the sliced bag after most of the bag contents have fallen through the perforated receiving basket and into a mixing tank. The apparatus is particularly useful for debagging acrylamide monomer in the production of polyacrylamide homopolymers and copolymers.
