ABSTRACT:
An apparatus shreds hazardous waste drums and their contents in an oxygen-limited environment, transports the shredded material to a dispenser that dispenses metered amounts of the material into fire pails. The apparatus has two vertically separated shredders that are located in an enclosed shell that has an inert gas fed into it in a controlled manner by a purge system. A lift in an enclosed shaft raises the drums, two at a time, and deposits them into an airlock from which they are released one at a time into the upper shredder. A control system automatically processes the material through the apparatus from when the containers are placed into the lift until the material reaches the dispenser and insures that no stage of the process will commence until the proceeding and following stages are completed. The control system also provides safety checks at each stage to prevent handling or processing accidents.
