Abstract

La machine de l'invention comprend un bâti, des moyens d'entraînement avec un élément rotatif et un support de coupe avec des mèches. L'élément rotatif est relié aux moyens d'entraînement qui l'entraînent dans un sens autour d'un axe longitudinal. Le support est monté sur l'élément libre en rotation autour de son axe longitudinal. La machine est ensuite placée pour que les mèches, l'élément étant entraîné en rotation, désagrègent le minerai. Le support de coupe est alors entraîné en rotation dans le sens opposé à celui de l'élément rotatif. L'invention permet d'éliminer la poussière et les étincelles produites généralement lors de l'abattage.
