ABSTRACT OF THE DISCLOSURE A plurality of discrete small cooling surfaces are arrayed on the surface of a journally or movablely received heat extracting member in both the axial and rotational directions. These discrete small cooling surfaces can be formed by a plurality of one set of parallel grooves formed between two axial ends and obliquely to the axial ends having been crossed by a plurality of the other set of parallel grooves formed in a similar manner but in different direction. An opening of nozzle means are directed toward the outer peripheral surface of the heat extracting member. A continuing stream of molten material is projected upon the discrete small cooling surfaces of the rotating heat extracting member, thereby the heat of the molten material is extracted by each of these discrete small surface and solidifies on it in a discrete flake particle. Since the discrete small cooling surfaces are formed in a number of arrays extending in both axial and rotational direction by crossing the one set of grooves with the other set of grooves, opening or openings of the nozzle means can be extended in long length in the axial direction of the heat extracting member or can be arranged as a plurality of nozzles in same direction. Accordingly, the molten material can be applied concurrently onto a plurality of discrete small cooling surface. By virtue of the apparatus of the construction, flake particles can be obtaiined at a greatly increased production efficiency.
