ABSTRACT:
A novel ball mill providing a maximum efficiency for the balls dropping onto the material to be crushed, this being obtained by associating a vertical tube into which said material is poured together with the ball with means for raising the balls and crushed material passing out of the lower end of the tube, so as to reintroduce same into the upper end of the latter, the sufficiently crushed material being sucked out of the tube at a selected point of its height.
