Abstract

Procedimiento para granular fusiones, tales como fusiones de escoria, fusiones de vidrio, fusiones de cerámica, fusiones de metales y fusiones de aleaciones de metales, en especial fusiones de escorias de altos hornos, mediante confluencia de la fusión con una corriente de partículas sólidas de grano fino, caracterizado porque la fusión se esparce en forma de película liquida delgada, siendo esta película transformada en un granulado sustancialmente de grano fino, mediante bombardeo con un chorro de partículas sólidas de grano fino.
