摘要： A centrifugal cleaner with a reject chamber (1) having a center dilution arrangement (3) with a dilution nozzle (4) to deliver dilution fluid to the reject chamber (1), and a reject outlet (7) at the bottom of the reject chamber (1). The dilution nozzle (4) points outwards to create a crossing outward flow of dilution fluid across an annular space (5) around the dilution arrangement (3) to slow circulating fluid flowing down from a cone (2) of the centrifugal cleaner to the reject chamber (1). The dilution arrangement (3) may have a clearing nozzle (6), directed against the reject outlet (7). The dilution nozzle (4) may be pointed below the bottom end (9) of the cone (2) and the dilution arrangement (3) may not extend higher than the bottom end of the cone.
