A method for producing flake particles by projecting a continuing stream of molten material upon the surface of a rotating generally circular, heat extracting drum, having a serrated edge with each serration comprising a radial surface and an angularly disposed connecting surface from the base of one radial surface to the peripheral extremity of the adjacent radial surface; and rotating the heat extracting drum at a speed relative to the size and shape of the serrations and relative to the rate of molten material projection to form a discrete flake particle on each angularly disposed surface; followed by removing each particle from the surface after each particle is at least partially solidified; and cooling the particles in a surrounding atmosphere. An apparatus for producing flake particles comprising means for projecting a stream of molten material upon a rotatable heat extracting drum member having a serrated generally circular peripheral edge, with each serration having a radial surface and an angular surface connecting the base of one radial surface with the peripheral extremity of the next radial surface; and a shaft supporting the heat extracting member for rotation at a controlled speed; with means responsive to the rate of projection of the molten material upon the serrated surface of the heat extracting member to control its speed of rotation relative to the rate of projection of molten material.

A method of producing flake particles from molten material, comprising: (a) rotating a heat-extracting drum having a serrated periphery, with each serration comprising surfaces that meet in an edge substantially parallel to the axis of rotation; (b) projecting upon said serrated periphery a stream of molten material to form a discrete flake particle on each serration while removing heat from the particle and at least partially solidifying said particle on said serration; (c) releasing said particle from said serration; and (d) cooling said particle in a surrounding atmosphere.
