A mold powder feeding apparatus which prevents adhesion and breakout phenomena of the mold powder or reoxidation of molten steel by feeding mold powder stably, has a mold powder-filtering function, and can feed the mold powder uniformly is provided. An apparatus for feeding a mold powder comprises: a storage tank for storing the mold powder; a mold powder transfer equipment for transferring mold powder stored in the storage tank by a conveyor belt; a filtration equipment for passing the transferred mold powder through a reticular filtration part by a rotary shaft that is rotated; a feeding equipment for feeding the mold powder filtered in the filtration equipment; an injection equipment for injecting the mold powder fed by the feeding equipment into a mold; and a drive equipment for driving the injection equipment by an air cylinder. The filtration equipment comprises: a reticular filter mesh(33) installed in a lower part of a casing(32) to filter mold powder; a shaft(30) which is installed in the casing and rotated by means of an O-ring(27) and a bearing(26), and in which holes(29) are formed to flow a gas; an impeller(28) fixed to a central position of the shaft; a mobile boss(23) connected to one side of the shaft in the state that an O-ring(24) and a bearing(25) are interposed between the mobile boss and the shaft to rotate the shaft; and a plurality of vanes(31) fixed to the other side of the shaft to distribute mold powder.
