GRAVITY MIXER Russian patent published in 2009 - IPC B01F13/00 B01F3/18 

FIELD: mechanics.

SUBSTANCE: gravity mixer consists of a cylinder-shaped taper-bottomed body with feed and discharge nipples. On centre inside the body there is a vertical pipe conduit mounted with tangentially hydraulic nozzles arranged at a specified spacing along it. Between the pipe conduit and the body wall there is a onefold discontinuous tape helix rigidly fixed. Under the last but one coil of the tape helix there is a slanted sieve bottom with a rubber compensator element positioned. Under the sieve bottom there is hammer installed to provide for periodical application of impact onto the sieve bottom rubber compensator element. Additionally the gravity mixer is equipped with a bucket conveyor for metal balls upward transportation. A slanted conduit connects the bucket conveyor bottom part to that of the gravity mixer (immediately at the lower edge of the slanted sieve bottom) and the bucket conveyor top part - to the gravity mixer lid.

EFFECT: enhanced energy efficiency of the mixing process, reduced specific energy consumption and improved operational reliability of the gravity mixer.
