Title (EN) AN AGITATED-MEDIA MILL WITH A BAFFLED INNER WALL
(FR) BROYEUR A MILIEU AGITE PRESENTANT UNE PAROI INTERIEURE A DEFLECTEUR
Abstract: front page image
(EN)An agitated-media mill of the batch, circulation, or continuous types in which the elements (18) of a comminuting media randomly interact in response to an agitator (12) having motion relative to the comminuting media to comminute a process mixture. Prior to the present invention, a need existed for a method and structure for establishing random motion of the comminuting elements, and for opposing the tendency of certain process mixtures to rotate as a solid with the agitator thereby establishing relative motion between the agitator and the comminuting media to comminute the mixture to be processed. In one embodiment, the radial members (62) of the agitator include non-circular baffle portions (64) that establish vertically oscillating flow of the mixture to increase the random interaction of the elements and improve comminution of the mixture. In another embodiment, the agitated-media mill includes a baffle (20a) or plurality of baffles adjacent the inner wall of the comminuting vessel and arranged transversely with respect to the flow of the process mixture. The baffles, which can be of varied shape depending on the particular media used, redirect the comminuting elements to increase the random interaction of the elements throughout the vessel and also oppose the solid body rotation of the process mixture to provide improved comminution of the mixture.
(FR)Un broyeur a milieu agite du type a charges, a circulation ou en continu, dans lequel les elements (18) d"un milieu a deviser reagissent au hasard en reponse a un agitateur (12) ayant un deplacement relatif par rapport au milieu a diviser. Prealablement a la presente invention se faisait sentir le besoin d"un procede et d"une structure pour etablir un deplacement au hasard des elements a dissocier, et pour s"opposer a la tendance de certains milieux en travail a tourner en accompagnant l"agitateur, en etablissant ainsi un deplacement relatif entre l"agitateur et le milieu afin de dissocier le milieu a traiter. Dans une mise en oeuvre, les pieces radiales (62) de l"agitateur comprennent des parties de deflection non-circulaires (64) qui etablissent un courant oscillant, vertical, afin d"augmenter la reaction au hasard des elements et ameliorer la division du melange. Dans une autre mise en oeuvre, le broyeur a milieu agite comprend un deflecteur (20a) ou une pluralite de deflecteurs adjacents a la paroi interne du recipient et disposes transversalement par rapport au courant du melange a traiter. Les deflecteurs, qui peuvent etre de formes diverses, selon le broyeur particulier utilise, redirigent les elements a diviser pour augmenter la reaction au hasard des elements dans l"ensemble du recipient et s"opposent ainsi a la rotation en bloc, du melange en travail afin d"obtenir une meilleure division du melange.
