FIELD: building materials industry. SUBSTANCE: the proposed device contains mill 1 with charging neck 2 and duct 3 connected through charging chute 4 with feeder 5 and discharge chute 6, which in its turn is connected with aspiration box. Dust extractor communicates from one side with the aspiration box and from the other via induced-draughted fan with atmosphere. The device is provided with a cooler and an air duct. Used for coarse cleaning is a dust condenser. The air duct is made up of two parts connected with each other through the induced-draught fan. The inlet of the fan is communicated with the space, where dust concentrate is removed from the coarse cleaning stage and its outlet is communicated through the dust concentrate cooler with the space under the charging neck box. Cross-section of the charging neck box relates to cross-section of the charging chute as 3 to 4. EFFECT: improved efficiency. 1 dwg
