ABSTRACT:
A drum is introduced into an interlock chamber and the interlock chamber is sealed. A door leading to a transition chamber is opened and the drum is moved into the transition chamber. The transition chamber is contained within a spool valve which includes a pair of drum grips. The drum grips are actuated to grasp the drum. The drum grips are rotatably coupled to an inner element of the spool valve. The inner element is rotated with respect to a housing and a drum manipulator grasps an end of the drum. The drum is displaced from the transition chamber toward a treatment chamber. The drum is cut into a desired shape and/or number of pieces with the drum and the material contained therein being deposited into the treatment chamber.
