FIELD: mechanical engineering.
SUBSTANCE: invention is designed for fine grinding of materials. Proposed tube mill contains cylindrical lined drum with coarse grinding chamber in form of lined perforated shell with outer diameter smaller than inner diameter of drum, and fine grinding chambers. Perforated classifying-feeding device is installed coaxially inside charging device stationary and with clearance relative to drum. Said classifying-feeding device follow constructively shape of charging device and adjoins, coaxially with alignment of central holes, interchamber partition installed at changing device. Ring chamber between perforated shell and lined drum accommodates stationary secured screw conveyor communicating with chamber located between charging device and interchamber partition. Hand of helix of conveyor screw from side of charging device is opposite to direction of rotation of mill drum.
EFFECT: intensified process of milling.
