Une Brokk 800 a remplac\u00e9 le dynamitage traditionnel par une d\u00e9molition m\u00e9canique constante, \u00e9liminant les risques pour la s\u00e9curit\u00e9 tout en maintenant la cha\u00eene de concassage en mouvement.<\/p>\n

\u00c0 la mine de minerai de fer de Malmberget en Su\u00e8de, LKAB a d\u00fb concasser des blocs de pierre surdimensionn\u00e9s avant qu'ils n'atteignent les concasseurs, \u00e0 1 250 m\u00e8tres sous terre, dans un environnement confin\u00e9.<\/p>\n

Les m\u00e9thodes de dynamitage traditionnelles \u00e9taient longues, co\u00fbteuses et pr\u00e9sentaient des risques pour la s\u00e9curit\u00e9. Brokk 800<\/a> Le remplacement des explosifs par la d\u00e9molition m\u00e9canique a permis aux op\u00e9rateurs de g\u00e9rer les mat\u00e9riaux surdimensionn\u00e9s de mani\u00e8re plus uniforme et de maintenir le processus de concassage en continu.<\/p>\n
