Abstract

A method of spraying a melt, preferably a metal melt, by disintegrating a stream of the melt by jets of fluid, for example gas or liquid jets, or jets of a mixture of gas and liquid, the which are directed at high pressure against the stream of molten material, characterized in that a first jet of fluid and a second jet of fluid, each extended in its own plane and formed of the same disintegrating fluid, are directed towards each other the other from the two opposites of the stream so that, while they still form substantially coherent jets, they intersect each other at an angle of 25º - 60 °, and because the stream of molten material is simultaneously directed against the first stream of fluid, such that, while still forming a substantially coherent stream, it cuts off the first stream of fluid at an angle of 30º - 60 °, preferably 40º - 45 °, at such a distance from the intersection of the first and second fluid jets that at least the main part of the molten material has time to change direction, due to the influence of the high kinetic energy of the first fluid jet, so that the main direction of that jet in the form of a layer of at least partially free droplets spread over the top of the jet, before the content of the stream, still in a molten state, reaches the intersection between the first and second fluid jets and finally be divided into free drops which, after solidifying, form the desired particles.
