Abstract

L'invention a pour but de fournir un procédé de fabrication de granulats carbonatés lourds et coulants, pour lequel la granulométrie de la matière première ne constitue aucun paramètre critique du processus. Ce but est atteint, conformément à l'invention, grâce au fait que le carbonate est granulé avec incorporation d'un composant liquide se présentant sous une forme liquide à pâteuse sous la pression normale et à des températures comprises entre 20 et 40 °C, la granulation s'effectuant dans un dispositif dans lequel on peut procéder, si on le désire, à une granulation en même temps qu'un séchage du granulat formé. Les granulats carbonatés obtenus suivant le procédé de l'invention présentent une masse volumique apparente d'au moins 400 g/l, de préférence de 500 à 1000 g/l.
