Title
(EN) BEATING APPARATUS FOR FIBRE SUSPENSIONS
(FR) APPAREIL DE BATTAGE DE SUSPENSIONS DE FIBRES
Abstract
(EN) A beating apparatus for fibre suspensions, including a housing (3) having at least one inlet (13) for suspension and one outlet (14) for beaten suspension, a rotor (9) rotatably arranged in the housing and having a beating surface, in which open perforations (10) extending through the rotor, and at least one stator (19) arranged in the housing and having a stator shoe (31) located close to the beating surface of the rotor. In order to prevent unbeaten suspension from reaching the outlet, shield and guide means (24; 35) is arranged between the inlet and the outlet, said shield and guide means leading all flow between the inlet and the outlet through the stator shoe (59).
(FR) Ledit appareil de battage comporte un boîtier (3) pourvu d'au moins une entrée (13) pour recevoir la suspension et une sortie (14) pour décharger celle-ci après battage, un rotor (9) monté rotatif dans ledit boîtier et équipé d'une surface de battage dans laquelle débouchent des perforations (10) qui traversent le rotor. Au moins un stator (19) est disposé dans le boîtier et un sabot de stator (31) est agencé près de la surface de battage du rotor. Pour éviter que la suspension non battue puisse atteindre la sortie, des moyens de protection et de guidage (24; 35) sont prévus entre l'entrée et la sortie, lesdits moyens de protection et de guidage conduisant l'ensemble de l'écoulement entre l'entrée et la sortie à travers le sabot du stator (59).
