A sieve device comprising a perforated sieve surface rotating around a central, vertical shaft (4), said sieve surface having the shape of a hollow, truncated cone casing with downwardly directed top, on which in the middle an impervious distributor cone has been mounted having an upwardly directed top, the basis of said cone joining the sieve surface, in which the supply of the mixture to be separated takes place via a central supply tube placed above the distributor cone, whereas the removal of the coarse component takes place near the circumference of the sieve surface, said central, vertical shaft being coupled with a drive set (S). The novel device comprises at least one spring device (14) in the drive set. |
