Slurry delivery conduit of mixer and slurry delivery method

摘要

The purpose of the present invention is to prevent the occurrence of a flow rate difference or a specific gravity difference in gypsum slurry between gypsum slurry delivery ports, and to divert a slurry flow and sufficiently ensure a separation distance between the slurry delivery ports without forming a slurry accumulation element in a branch part. A slurry delivery conduit (10) comprises a straight conduit path (14), a branch part (15), and branch conduit paths (16). A conduit wall joining part (20) of the branch conduit paths forms a V-shaped countercurrent dividing element (22) in the branch part. Gypsum slurry in a kneading area (51) is introduced into the straight conduit path forming a straight flow path. The straight conduit path rectifies the flow of the gypsum slurry into an axial flow or a straight flow (S), and the axial flow or the straight flow is divided into branched flows (S1 and S2) by the countercurrent dividing element.
