Abstract
Improvements in certain ball mills, in which at least a part of the material crushed by the movement of friction and fall of grinding bodies, is removed from the grinding chamber by air flow, characterized in that said chamber is composed of a conical grinding bowl (1) rotating by means of a vertical axis and centrally fed with new material, and of a fixed cap (2, 2', 2 ") disposed above the bowl which on its periphery carries holes for air intake (8) and upper internal surface traced to return to the center of the bucket the grinding bodies (10) and the material that still needs to be ground.
