Abstract (en)

[origin: EP0084878A2] 1. Sieving method wherein the oscillations imparted to the sieve box extend essentially vertically to the sieve plane, characterized in that these oscillations incite flat springs (4) arranged below the sieve plane vertically to the oscillation plane (6) and vertically to the direction of the sieving material overflow (5) on supports fixed within the sieve box to perform resonant modes (7) whose effective amplitudes extend essentially unilaterally of the sieve bottom (2) and that the flat springs (4) in addition to their vertically directed motion (7) travel to and for horizontally within a predetermined travelling space (8).
