To provide a device for centrifugal spray allowing for suppressing size increase.SOLUTION: A device for centrifugal spray 1, for producing a fine metal powder by supplying a molten metal M to a rotary disk 21 and spraying it outward of the rotary disk 21 into solidification through imparting a centrifugal force to the molten metal M, comprises a supply unit 32 that supplies the molten metal M to the rotary disk 21, a temperature detecting unit that detects a temperature of the rotary disk 21, and a supply control unit that controls a tapping part 32 to increase/decrease the per-time feed rate of the molten metal to be supplied from the supply unit to the rotary disk 21 depending upon a detection temperature of the temperature detecting unit.SELECTED DRAWING: Figure 1 【課題】大型化を抑制できる遠心噴霧装置を提供する。【解決手段】溶融金属Ｍを回転ディスク２１に供給し、前記溶融金属Ｍに遠心力を与えることで前記回転ディスク２１の外方へと噴霧して固化させることにより、金属微粉末を製造する遠心噴霧装置１であって、前記溶融金属Ｍを前記回転ディスク２１に供給する供給部３２と、前記回転ディスク２１の温度を検出する温度検出部と、前記温度検出部の検出温度に応じ、前記供給部から前記回転ディスク２１に供給される前記溶湯の時間当たり供給量を増減するよう前記出湯部３２を制御する供給制御部と、を備える。【選択図】図１
