FIELD: separating solids from solids. ^ SUBSTANCE: device comprises vertical air-separating passage, units for supplying the initial mixture and auxiliary gas flow, and unit for discharging the bottom and top fractions. The vertical air-separating passage has the round cross-section and is made of two sections for permitting variations of its height. The unit for supplying the initial mixture is made of a branch pipe connected to the housing of the device through a pivoting member for permitting variations of the angle of its inclination to the vertical axis from 35° to 55°. The unit for supplying auxiliary gas flow is mounted so that to provide air to flow contrary to the direction of the discharged bottom fraction. The unit for discharging the bottom fraction is made of two section for permitting variation of its length. ^ EFFECT: enhanced efficiency, simplified structure, and reduced metal consumption. ^ 1 cl, 1 dwg |
