DEVICE FOR UNIFORM DRAW-DOWN, HOMOGENIZATION AND CONTINUOUS MIXING OF BULK SOLIDS FROM SILOS AND STOCKPILES

Discharge device consisting of inner (1) and outer tubes (6) with inlet openings/slots (5, 8) for the solids feed from the silo and an outlet for the same. The inner tube is provided with a helical screw flight (2) attached to its inside. The screw flight may have a central shaft. The telescopic outer tube with slots can be used to vary the slot size as required, by rotating on the inner tube. While discharging the bulk solids, the outer and the inner tube with helix fixed inside it? es in the same direction powered by a single motor. The slots of the outer tube may be ?ed at exactly the same location as the slots on the inner tube or may be distributed unevenly and/or with different slot dimensions. The slots also can be provided with slight protrusions for digging into solids. The device can be installed at an angle of inclination between 1.degree. and 10.degree.. The device is suitable as a homogenizer, continuous mixer, device for reclaiming solids from silos and stockpiles.
