Process for agglomerating industrial dusts consisting of: - kneading in a vat the dusts to be agglomerated in the presence of a first binder comprising a polymer with a molecular weight above 500,000 g/mol, which is in the form of a reverse emulsion, - then adding to the vat separately, while still kneading, a second binder comprising a silicate of an alkaline metal, and - finally compacting the resulting agglomerates under pressure.
Procédé d'agglomération de poussières industrielles consistant : à malaxer dans une cuve les poussières à agglomérer en présence d'un premier liant comprenant un polymère de poids moléculaire supérieur à 500.000 g/mol, se présentant sous la forme d'une émulsion inverse; puis à ajouter séparément dans la cuve tout en malaxant, un second agent liant comprenant un silicate de métal alcalin, enfin à compacter par pression les agglomérats obtenus.
