BULK MATERIAL SEPARATOR Russian patent published in 1999 - IPC

FIELD: agriculture, in particular, grain separating equipment. SUBSTANCE: bulk material separator has perforated cylindrical drum and drive rotor mounted within perforated drum. Rods are fixed to rotor so as to form rows extending in parallel with rotor axis. Gap is defined between rod ends and perforated drum surface. Separator is further provided with devices for charging basic material and discharging products of separation. Axis of perforated drum is inclined relative to horizontal position and drum is mounted for rotation about its geometrical plane and axis and is equipped with individual drive. Drum perforations are made round. Rods are manufactured from resilient material and have S-shaped diametrical section. Gap between rod ends and drum surface is reducing from drum surface to device for discharging products of separation. Rod spacing in each row exceeds size of perforations. EFFECT: increased efficiency in grain separation by improved loosening of bulk material and advancement of small particles to perforations. 2 dwg
