Abstract (en)

[origin: WO8805341A1] A tube ball mill comprises a casing provided with an inlet and outlet for the ground material, in which annular diaphragms (4, 5, 6, 7) of ellipsoidal form are mounted at an angle $g(a) to the longitudinal axis (3) of the casing (1). The pitch between the adjacent annular diaphragms (4, 5; 5, 6; 6, 7) is slightly more than D/tg$g(a), where D - is the internal diameter of the casing, $g(a) - is the angle of inclination of the annular diaphragm (4, 5, 6, 7) in relation to the longitudinal axis (3) of the casing (1).
