Abstract

The sieve is set into elliptical oscillation by two different unbalancing weights (9, 10) which rotate at the same speed in opposite directions. The weights are supported by shafts (16, 17). The shafts are pivoted (13, 14) to a pair of gears (12) which remain stationary in relation to the oscillating sieve.
