Star or disc sieve arrangement, comprising a plurality of sieve disc shafts

摘要

The arrangement has several driven sieve shafts (1) with tools (2) and/or end plates (3). Spacer elements (4) between the tools and/or the end plates have a double truncated cone-shape or a mainly parabolic rotary surface. Opposite surfaces are symmetrical relative to the spacer sleeve length, or the shaft sections between the plates have the above shapes and form such spacer elements. Spacer elements with tool plates are positioned on the shafts so that the plates of neighboring shafts project into the area of smallest diameter of opposite spacer elements.
