METHOD OF PREPARATION OF MIX OF LOOSE MATERIALS AND DEVICE FOR ITS REALIZATION Russian patent published in 1999 - IPC

FIELD: preparation of mix of loose materials. SUBSTANCE: destruction of the nucleus of segregation at preparation of mix is accomplished by displacement of element changing the trajectory of components being mixed in the cross and longitudinal sections of the mixer. Coaxially installed inside the drum of the device for preparation of mix of loose materials is a shaft connected to the rotation drive, which carries a bent duct connected to the axial displacement drive, its side edges are located at definite distances from the shaft axis on its one side equals 0.5 to 0.7 R, and on the other side - 0.8 to 0.9 R, where R - drum inside radius. The duct is installed for changing the angle of its inclination to the axis of rotation. EFFECT: enhanced quality of mixing of various mixes, and enhanced capacity without essential complication of mixer design. 5 cl, 3 dwg
