Abstract
L'invention concerne un procédé et un dispositif pour
séparer diverses particules de matériaux.
On expose les particules à trier à deux phénomènes diffé
rents, à savoir un phénomène mécanique tel que la pesanteur
définissant une trajectoire de base 3, et un phénomène élec
trique tel qu'un champ magnétique glissant ou des forces de
Laplace 4 engendrés par un inducteur 2 capable de faire
dévier les particules de leur trajectoire de base.
Application: Séparation de particules de matériaux
conducteurs magnétiques, conducteurs amagnétiques et/ou
non conducteurs.
