Abstract

RETRITURACION DE LOS MIXTOS EN UN PROCESO DE PREPARACION DE UN PRODUCTO DE MINERAL DE LA CLASE EN LA QUE EL MIXTO SE REMUELE EN ORDEN A TRITURAR MEDIOS GRANOS INDIVIDUALES Y DESPRENDER EL MINERAL DE MAS VALOR, ESTO SE LLEVA A CABO EN UN MOLINO USANDO UN MEDIO DE TRITURACION AGITADO. EL MIXTO SE REDUCE HASTA UN TAMAÑO DE PARTICULAS MAS PEQUEÑO QUE K80=100(MU)M. SE USAN CUERPOS DE TRITURACION CON UN TAMAÑO MEDIO DE 2 A 6 MM.
