Abstract

Procédé de préparation de mélanges contenant 60 à 85 % de charbon broyé 15 à 40 % d'eau et au moins un additif. L'additif est ajouté progressivement pendant le broyage du charbon. La quantité d'additif correspond à chaque moment à la surface spécifique disponible. Process for the preparation of mixtures containing 60 to 85 % ground coal 15 to 40% water and at least one additive. The additive is added gradually during the grinding of the coal. The quantity of additive corresponds to each moment to the specific surface available.

Les mélanges charbon-eau préparés selon l'invention sont des liquides pompables, faciles à transporter. The coal-water mixtures prepared according to the invention are pumpable liquids, easy to transport.
