GRAVITY MIXER OF LOOSE MATERIALS Russian patent published in 2024 - IPC B01F23/60 B01F25/83 

FIELD: various technological processes.

SUBSTANCE: invention relates to equipment for mixing loose materials and can be used in construction, chemical, pharmaceutical, food and other industries. Gravity mixer of loose materials comprises a cylindrical housing with a conical bottom, branch pipes for loading initial components and unloading the finished product, material flow distributor in the form of a cone with helical blades, upper and lower transfer funnels installed in height with a gap relative to each other in a projection on a vertical plane, and guide funnels in the form of a truncated inverted cone, alternating in height upper and lower transfer funnels are made in the form of axisymmetric high, starting from the outer cone, and low truncated cones in adjacent rows, angle of inclination of generatrices to vertical is equal to 25…35°, wherein high and low cones differ in height by 2.0…2.5 times, the upper transfer funnel consists of inverted truncated cones installed with a large base upwards, and the lower funnel is from truncated cones installed with a large base downwards, wherein the truncated cones of the transfer funnels are installed with an annular gap relative to each other in a projection on the horizontal plane, in adjacent annular gaps curved blades with opposite inclination are fixed, besides, direction of inclination of curved blades in annular gaps of upper and lower transfer funnels is opposite, and guide funnels are connected to upper end of outer truncated cone of lower transfer funnels.

EFFECT: higher efficiency of mixing loose materials.
