ABSTRACT:
An apparatus and method for mixing a fluid, such as chlorine or oxygen gas, into a suspension, such as comminuted cellulosic material. A circular cross-section conduit defines a flow path for a suspension, and a circular smooth-faced disc is mounted in the conduit for rotation, covering substantially the entire interior of the conduit. A relatively small opening extends through the disc, and that disc is rotated in the conduit with small portions of suspension flowing in the conduit progressively passing through the opening and being fluidized when passing through the opening. The fluid is introduced into the suspension as the suspension flows through the opening, and in this way an even distribution of fluid in the suspension, with minimum power consumption, is provided.
