Abstract

PROCEDIMIENTO PARA EL TRATAMIENTO SELECTIVO DE REGENERACION DE ARENAS USADAS DE FUNDICION, EN EL QUE SE EFECTUA UNA SEPARACION DE PORCIONES DE LOS AGLUTINANTES A PARTIR DE LA MASA GRANULAR BASICA MEDIANTE MEDIOS MECANICOS Y A CONTINUACION LOS GRANOS DE ARENA SE ACELERAN DE MODO QUE SE PRODUCE UN EFECTO DE FRICCION DE LOS GRANOS DE ARENA INDIVIDUALES ENTRE SI. DESPUES SE EFECTUA UNA SEPARACION ENTRE GRANOS GRANDES Y PEQUEÑOS Y A CONTINUACION SE CONTINUA TRATANDO EVENTUALMENTE.
