Zusammenfassung:	FIELD: fine grinding technique. ^ SUBSTANCE: drum-type ball mill has hollow lined drum, charging and discharge device, perforated discharge grid positioned at drum outlet end, and recycle pipe rigidly attached to drum. Recycle pipe consists of inner and outer truncated hollow cones coaxially arranged relative to one another. Each of said cones is open at both ends. Truncated cones are oriented in opposite directions with their larger bases. Inner hollow truncated cone is made perforated and is directed with its larger base toward charging device. Device for feeding of material into recycle pipe is made in the form of lifters arranged lengthwise of recycle pipe. ^ EFFECT: increased efficiency in milling of materials. ^ 3 cl, 1 dwg
