Abstract

Procédé de préparation d'un mélange pulvérulent. En mélangeant un résole liquide 1 et une charge 2, on prépare dans un stade 3 une suspension que l'on mélange à son tour en un stade 5 à l'aide d'un liquide 4 de séparation. On décante en 6 et sèche en 7 tout en neutralisant l'eau en 8 que l'on élimine sous forme d'eau résiduaire en 9. Industrie métallurgique.
