Abstract

L'invention concerne un broyeur à boulets doté d'un agitateur comprenant un contenant de broyage et un arbre agitateur rotatif sur lequel sont disposés plusieurs éléments broyeurs. Les éléments broyeurs sont fixés à l'arbre en étant mutuellement espacés d'une certaine distance. Cette distance permet de former un espace intermédiaire dans lequel sont disposés plusieurs éléments additionnels. Dans l'espace intermédiaire, les éléments additionnels sont placés sur l'arbre agitateur individuellement et/ou par paires.
