FIELD: paper making by aerodynamic method, equipment for transportation of fiber aerosuspension. SUBSTANCE: device has cylindrical body with supplying channels tangentially located along body axis and ensuring free supply of aerosuspension flows from several dispersers and discharge channel for supply of aerosuspension onto wire. Rotor accommodated in body and made in form of cylinder with blades attached radially to its external surface forms zone of active displacement. Making of supplying channels in form of diffuser-confuser passages results in axial redistribution of aerosuspension and acceleration of mixing process. Making in discharge channel at body outlet of elbow which turns discharge channel in direction opposite to direction of rotor rotation prevents fiber clots from getting onto wire. Staggered location of blades provides for additional conditions for axial redistribution of aerosuspension flow to improve mixing. As a result, supplied to wire from discharge channel is aerosuspension flow with uniform distribution of fiber over entire width of formed web. EFFECT: higher homogeneity of structure of formed paper web with simple design of device. 4 cl, 3 dwg
