A device for separating multi-fraction particulate materials includes a housing with an inner passage for admitting the material to be processed and an outer passage having an outlet and connected to a suction device for producing an air stream in an upward direction. A guide body with a conical surface and a shoulder having an edge are mounted in the housing. The second passage has in the region below the shoulder a zig-zag shaped passage portion. The incoming stream of mixture falls on the conical surface, then on the edge of the shoulder and then is discharged into the zig-zag shaped portion so that when suction is applied to the outlet of the outer passage the material undergoes repeated directional changes during each of which the air stream travels transversely through the material.

Pneumatic separator for flowable particulate materials

A separating apparatus has a frame comprised of a stationary lower frame and a tiltable upper frame. A pair of longitudinally independently displaceable tables are spring-biased into respective central positions on the frame and are each displaceable in either longitudinal direction from these central positions. A drive assembly comprises an electric motor operatively connected to a crank pin that is rotated so as to move longitudinally relative to the frame. A link is connected between this crank pin on the front table and the rear table so that the two tables are moved oppositely longitudinally relative to each other when the motor operates. A stabilizer including a two-arm lever pivoted on the frame and having a pair of arms each connected via a respective stabilizing link to a respective table may be provided in the arrangement in order to insure that the strokes of the two tables remain at a fixed ratio to each other.
