Summary:A metal powder producing apparatus 10 comprising a cylinder body 32 provided beneath a molten metal supply 20, and a cooling liquid layer forming part providing a flow of cooling liquid 50 along an inner face of the cylinder. The cooling liquid layer forming part comprises a nozzle 37 forming a flow of liquid towards the inner side of a radial direction from the inner cylinder face, and a frame 38 provided to the inner cylinder face 33 with which the flow of liquid collides in order to change flow direction from radial to along the inner face 33. The inner diameter of the frame 38 is smaller than that of the inner face 33 but may increase in a tapered form towards the axially lower end of the frame. Cooling liquid discharges from the gap 52 between the frame 38 and face 33. The frame 38 may be provided on an upper part of the cylinder body 32. A metal powder producing apparatus as described but where the nozzle forms a spiral flow of cooling liquid is disclosed. Methods of producing metal powder using both ap
