Abstract
Official abstract text for this publication.
A pulper for comminuting and suspending fibrous material includes a container and at least one rotor arranged in the container for circulating a fibrous material suspension located on the container and at least one rigid sieve. The rotor at least predominantly passes over the sieve surface which is provided with round sieve openings. As high a throughput as possible and as low an energy consumption as possible are to be achieved by limiting the cross-section of the sieve openings exclusively defined by circle segments.
