Abstract
A mixer apparatus, and procedure, for mixing medium consistency (e.g., 6-15%) paper pulp, or like fibrous suspension, minimizes the power necessary to effect fluidization, and minimizes the speed for rotation of the rotor to effect fluidization. This is accomplished by preventing the formation of a shadow behind the rotor ribs as they rotate within the mixer housing, and similarly by preventing the formation of a shadow behind the stationary ribs formed on the housing (and cooperating with the rotating ribs). Such shadows are prevented by providing one wall of each of the ribs--the trailing wall in the direction of rotation of the rotor--so that it is sloped, and fills the volume the shadow would occupy.
