Tubular ball mill

The tubular ball mill is divided in an inclined partition into coarse- and fine-grinding chambers with grinding bodies. Material passage holes are also provided in the mill where the partition makes contact with the bodies in the coarse-grinding chamber. The holes (12) should have a length (1) considerably greater than their width (a) and should be arranged so their long side (13) runs parallel to the partition contour (11). Preferably the length is 25 times the width, and the short sides (14) of the holes are bevelled toward the fine-grinding chamber. - The holes can expand towards the fine-grinding chamber where the long side forms an angle with a plane perpendicular to that of the partition and equal to the partition angle. The coarse-grinding chamber zone (17) clear of the bodies, also has holes (18) whose long side is parallel to the short axis (20) of the partition ellipse with the axis of symmetry parallel to the mill axis.
