A device for converting a stream of a slurry or liquid flowing down a tube into a flat stream having a uniform flow across its width and, if a slurry, a uniform particle size distribution across that width. The device comprises a vertical tube from which the slurry or liquid may flow onto a horizontal first plate in an even laminar flow and a second plate adapted to receive medium flowing over the edge of the first plate disposed below the first plate and inclined relative thereto. Metering of the amount of medium flowing onto any one increment of the width of the second plate so that it will be substantially equal to the amount of medium flowing down any other increment of equal width is achieved by the use of a first plate having a closely defined peripheral shape or by the use of vertical dividing members spaced around the periphery at uniform angular spacings which direct the medium onto equal width increments of the second plate.
