PULPER

摘要

The invention relates to a pulper for comminuting and suspending fibrous material (F), consisting of a container (2) and at least one rotor (4) arranged in the container (2) for circulating a fibrous material suspension (1) located in the container (2) and at least one rigid sieve (3), wherein the rotor (4) at least predominantly passes over the sieve surface provided with round sieve openings (6). 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 (6) exclusively by means of circle segments.
