Abstract

Process for the preparation, from melts, of compounds and/or mixtures of dry and organic and inorganic compounds, containing less than 1.5% of adsorbed moisture, consisting of individual particles, characterized in that collides a dispersed solid inoculating substance together with the droplets formed by atomizing the melt in a stream of inert gas at 20 to 80ºC, the moisture content of which is eventually adjusted to a certain value, the formed solid product is removed and eventually part of it is returned to the process as inoculation substance, while the remaining part, eventually after classification, is obtained as a finished product.
