Abstract

PROCEDIMIENTOS MEDIANTE LOS CUALES UNA MEZCLA DE DOS O MAS MATERIALES EN PARTICULAS DISTINTOS, CADA UNO DE LOS CUALES MATERIALES TIENE UN DIFERENTE COEFICIENTE DE FRICCION EN DESLIZAMIENTO, SE PUEDE SEPARAR UTILIZANDO METODOS QUE APROVECHAN LAS DIFERENCIAS DE VELOCIDADES GENERADAS POR APLICACION A UNA FUERZA DE DICHA MEZCLA PARA CREAR EL MOVIMIENTO DE DICHA MEZCLA SOBRE UNA SUPERFICIE EN FUNCION DE SU COEFICIENTE DE FRICCION EN DESLIZAMIENTO. SE DESCRIBEN TAMBIEN DIVERSOS APARATOS PARA EFECTUAR TALES SEPARACIONES.
