Title
(EN) METHOD FOR AGGLOMERATING INDUSTRIAL DUST, IN PARTICULAR USING A BRIQUETTING TECHNIQUE
(FR) Procédé d'agglomération de poussières industrielles, en particulier par technique de briquetage
Abstract
(EN)
The invention relates to a method for agglomerating industrial dust comprising: mixing the dust to be agglomerated in a vat in the presence of a first binder including a polymer with a molecular weight of more than 500,000 g/mol, presented in the form of a reverse emulsion; then separately adding a second binding agent, including an alkaline metal silicate, to the vat while continuing to mix; and finally compacting the obtained agglomerates under pressure.
(FR)
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.
