Abstract
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 co…
