A system and method for producing foundry quality sand from non-conventional starting materials through the combination of oolitization and classification. Incoming particulate matter is first directed into a controlled energy attrition unit (20) where the particles are made to collide with one another. Such collisions clean and round the particles by chipping away surface projections and coatings without crushing the particles. The particle stream is then directed through a multi-fraction classifier (30) where it is separated into two or more useable grades of foundry sand. An air classifier is preferred for the classification stage.
L'invention porte sur un système et un procédé de production de sables de fonderie à partir de matériaux non traditionnels par combinaison d'oolitization et de tri. A cet effet le matériau particulaire entrant passe d'abord dans une unité contrôlée d'attrition où les particules sont amenées à s'entrechoquer. De telles collisions nettoient et arrondissent les particules sans les écraser en en rabotant les parties saillantes et le revêtement. Le flux de particules passe ensuite dans une trieuse des différentes fractions, où elles sont séparées en deux ou plusieurs catégories utilisables de sables de fonderie. On utilise de préférence une trieuse pneumatique pour leur répartition en catégories.
