Abstract

Procédé et dispositif permettant d'éviter l'agglomération de fibres sèches de diamètres et de longueurs compris dans des gammes déterminées pendant le mélange desdites fibres dans un matériau particulaire sec ou mouillé. Le procédé consiste à distribuer des fibres dans un milieu à l'état de vapeur, et à transporter des fibres fluidisées jusqu'à une zone de mélange contenant un matériau particulaire sec ou mouillé. Simultanément à l'agitation et au mélange du matériau particulaire avec les fibres fluidisées, celles-ci, ayant été séparées au moins partiellement de la vapeur fluidisée, sont introduites graduellement dans la zone de mélange. Ce procédé évite le phénomène d'agglomération se produisant autrement avec certaines fibres.
