Abstract
A separator for separating coarse particles from cellulose pulp suspensions and the like comprises a first separation chamber provided with an inlet for incoming mixture, a first outlet for the light fraction, and an outlet for an intermediate fraction enriched in coarse particles. A second separation chamber is provided with a second inlet, a second outlet for a light return fraction, and an outlet for separated heavy fraction, the outlet for intermediate fraction being connected to the second inlet leading from a first zone in the first separation chamber. Said zone has a higher pressure than a second zone connected to the second outlet, the second zone being located in the first separation chamber or connected to the latter, the first and second separation chambers thus communicating to form a circuit.
