An apparatus for controlling the flow rate of powder raw material is disclosed. According to an embodiment of the present invention, the apparatus for controlling the flow rate of powder raw material comprises: an injection container which is filled with powder raw material; an air current transporting gas supply device which supplies air current transporting gas in order to supply the powder raw material inside the injection container to a high pressure reactor through air current transporting; a fluidization nitrogen supply device which supplies fluidization nitrogen gas in order to fluidize the powder raw material during the air current transporting of the powder raw material; a differential pressure measuring device which measures the differential pressure between the injection container and the high pressure reactor; a differential pressure maintaining unit which consistently maintains the differential pressure between the injection container and the high pressure reactor; and a powder raw material flow rate control unit which is connected with the fluidization nitrogen supply device in order to control the fluidization and the flow rate of the powder raw material.
