Abstract: L'invention concerne un dispositif et un procédé permettant d'extraire des particules ferriques d'un écoulement de matière introduit dans le dispositif (1). Ledit dispositif (1) comprend un logement (3) qui maintient un rouleau aimanté avec lequel l'écoulement de matière est mis en contact de manière à extraire les particules ferriques. Le rouleau (11) présente une surface extérieure (13) qui permet d'extraire et de capturer les particules ferriques entraînées le long d'une voie de passage fortement aimantée (15) formée par une spirale s'étendant le long de la surface extérieure (13) du rouleau (11) et la contournant. La spirale peut être un pole magnétique exposé exerçant une force magnétique radiale induite par un noyau d'aimant en contact avec la spirale sur les particules ferriques entraînées dans l'écoulement de matière, attirant ainsi les particules vers les pôles magnétiques sur la voie de passage. Un nettoyeur non-ferreux (17) est mis en contact avec le rouleau; il pousse les particules ferriques capturées à suivre la voie de passage vers une extrémité de la surface du rouleau où la force magnétique radiale de la voie de passage est réduite afin de permettre l'extraction des particules capturées du rouleau dans une zone de collecte.

Abstract: A structure of circular saw in which the critical number of revolution is no t lowered even if the saw is made thin but can be doubled as compared with a conventional circular saw by solving the drawback of prior art that the critical number of revolution decreases as the circular saw is made thinner to cause buckling, and a method for fixing a circular saw to a main rotary spindle. Three slits are made in the body of a circular saw having a central hole to extend radially from the central hole or the vicinity thereof at a required angle, and the end of the slit is set within an annular range of 60 - 75% of the radius at the bottom of the circular saw. When such a circular sa w is fixed to a main rotary spindle, the circular saw is clamped from the opposite sides by means of a pair of flanges provided on the main rotary spindle such that movement of the body of circular saw is restricted in the thickness direction but radial enlargement/contraction incident to expansion/shrinkage of the body is allowed.
