An object of the invention is to prevent differences in the flow rate and the specific gravity of a gypsum slurry from being caused between slurry discharge ports, to divide a current of the slurry into streams without a factor of stagnation of the slurry provided at a branch part, and also, to ensure a sufficient distance between the discharge ports. The slurry delivery conduit (10) has a rectilinear tube segment (14), a branch part (15) and branch tube segments (16). A tube-wall joint portion (20) of the branch tube segments configures a counter-flow splitting element (22) in a form of V-letter at the branch part. The slurry is introduced from a mixing area (51) into the rectilinear tube segment, which configures a straight rectilinear fluid passage. The rectilinear tube segment rectifies a flow of the slurry to be an axial or rectilinear current (S), and the axial or rectilinear current is split into branch streams (S1, S2) by the counter-flow splitting element.

System and method for dispensing a flowable product are provided. The system includes a mixing chamber having a first inlet, a second inlet and an outlet.
