The utility model relates to an ore slurry flow divider, which comprises an ore slurry container, wherein the bottom of the ore slurry container is provided with an opening; the lower part of the opening is provided with a distribution plate; and the distribution plate is provided with a plurality of ore slurry outlets. The opening is provided with a flow stabilizing plate which is provided with a plurality of through holes in the circumferencial direction; the central position of the flow stabilizing plate is provided with a rotatable rotating shaft in a penetrating way; the bottom end of the rotating shaft is provided with a cone; and a plurality of spiral blades are arranged on the conical surface of the cone. A peripheral wall and an inner wall which are concentric and are in a cylindrical surface shape are arranged on the distribution plate; the circular space between the peripheral wall and the inner wall is divided into a plurality of circular arc-shaped flow dividing grooves by a plurality of flow dividing plates; the bottom of each flow dividing groove is provided with one ore slurry outlet; and an inversed cone-shaped bottom is arranged in the inner wall. The ore slurry flow divide can reliably distribute ore slurry flows according to the ore slurry amount required in each branching process and can not generate the situation that ore easily deposits in the flower divider. The utility model has the advantages of simple structure, convenient operation and maintenance, and the like.
