(FR) AMELIORATIONS DES TAMBOURS D’UN BROYEUR
Abstract
(EN)
The present invention relates to hogger and reducing apparatus and considers issues associated with fibrous and other materials clogging screening apertures (407). The use of a paddle arrangement (401) having an open framework is discussed, this arrangement (401) rotating relative to the screening apertures (407) provided on a drum (40). Either or both the paddle arrangement (401) and drum (40) may rotate, the resultant action increasing agitation of raw material (being reduced in size by a reducing means) in the vicinity of the screening apertures (407) and also providing a wiping type effect to help clear material from within the apertures (407). Use of paddle arrangements in inclined and vertical type hoggers is discussed.
(FR)
La présente invention concerne un broyeur et un réducteur et considère les questions associées aux matières fibreuses et autres bouchant les ouvertures de tamisage (407). L’utilisation d’un malaxeur (401) présentant un cadre ouvert est abordée, cette disposition (401) tournant par rapport aux ouvertures de tamisage (407) prévues sur un tambour (40). L’un ou l’autre ou les deux agencements du malaxeur (401) et du tambour (40) peuvent ainsi tourner, l’action résultante augmentant l’agitation de la matière première (étant réduite en taille par des moyens de réduction) à proximité des ouvertures de tamisage (407) et prévoyant également un effet de type balayage pour favoriser le retrait de la matière de l’intérieur des ouvertures (407). L’utilisation du malaxeur dans des broyeurs de type incliné et vertical est discutée.
