ABSTRACT:
A ball-tube mill includes a rotatable drum enclosed at the opposite sides by bottoms having a charging port and a discharge port, the drum accommodating an even number of perforated walls having the form of an ellipse, arranged at an angle to the centerline of the drum, and offset along the like axes of the ellipse one relative to another to define milling chambers occupied by grinding bodies. The bottoms are inclined to the longitudinal centerline of the drum at an inclination angle equal to the angle of inclination of the perforated walls, each bottom and one of the perforated walls being inclined in pairs to the opposite directions, the bottoms and the perforated walls being successively offset along the like axes of the ellipse one relative to the other at an angle .beta.=360.degree.:n, where n is the total number of bottoms and perforated walls.
