Abstract

L'invention permet de contrôler l'écrasement de morceaux de minerais sans détérioration des éléments recherchés qu'ils contiennent. Les blocs de minerais passent entre un cylindre d'acier 2 et un cylindre 7 pourvu d'un revêtement élastique 8. La pression exercée par les cylindres est réglable au moyen de ressorts 13 sollicitant le cylindre 7 suspendu au balancier 11. L'invention s'applique notamment aux conglomérats contenant des diamants.
