Zusammenfassung:	FIELD: equipment for fine dry milling of solid materials. ^ SUBSTANCE: tube mill has drum divided by partition into coarse milling chamber and fine milling chamber, charging and discharge devices, perforated discharge partition, recycle tube open at both ends and equipped with screw blades having coils oriented in direction opposed to that of drum. Devices for supplying of material into recycle tube are made in the form of lifters. Each of said lifters have side adjoining to end rigidly attached to inner surface of drum and provided with opening for passage of material to be ground into lifter cavity. Said openings are closed with grids rigidly fixed on lifters and adapted for preventing milling bodies from getting into lifters. ^ EFFECT: increased efficiency of milling process. ^ 4 cl, 3 dwg
