CA 2059329

A method of electrically separating differing shapes of abrasive grain materials by imposing a high voltage corona induction charge to free-falling abrasive particles, polarization thereof and attraction thereof to a high voltage oppositely charged electrical field is disclosed, along with apparatus by which the method is practiced and the characteristics of shape of the particles of abrasive grain materials so separated.

Cette invention concerne une méthode de séparation électrique de grains abrasifs de différentes formes en imposant à des particles abrasives en chute libre une charge haute tension par induction à effet de couronne, en les polarisant et en les attirant au moyen d'un champ électrique haute tension de signe contraire. L'invention concerne également le dispositif servant à mettre oeuvre ladite méthode, ainsi que les caractéristiques de forme des particules abrasives ainsi séparées.
