DEVICE FOR FRACTIONAL SEPARATION OF RAW WASTE LUMBER Russian patent published in 1999 - IPC

FIELD: applicable in various processes in combination with forest exploitation equipment. SUBSTANCE: the device has a frame, installed in which are shafts for rotation from a drive; the longitudinal axes of the shafts are parallel to the disks located in checkered order on the adjacent shafts. In circumference the disks have oblique recesses made at an acute angle relative to the plane of the disk peripheral surfaces with alternation of their direction to the right, left, and knives are attached on two projections that are opposite in diameter. The speed of rotation of each subsequent shaft with disks exceeds that of the previous one. EFFECT: enhanced intensity of separation, orientation of particles and chips, and enhanced efficiency of fractional separation of raw waste lumber. 3 cl, 3 dwg
