Abstract
METODO PARA DETERMINAR EL VALOR DE UNA PROPIEDAD DEL MATERIAL QUE SE ENCUENTRA DENTRO DE UN MOLINO DURANTE LA TRITURACION DEL MATERIAL SOLIDO QUE SE ENCUENTRA EN EL MISMO, QUE CONSTA DE LOS SIGUIENTES PASOS: (A) DETECTAR LA INTENSIDAD DEL RUIDO DE LA MOLIENDA MEDIANTE UNA SEÑAL ELECTRICA ANALOGICA, CUYA INTENSIDAD ES PROPORCIONAL A LA INTENSIDAD DEL RUIDO EN EL CAMPO DE FRECUENCIA AUDIO, CONVIRTIENDO LA SEÑAL ANALOGICA EN SEÑAL DIGITAL; (C) PASAR LA SEÑAL DIGITAL A TRAVES DE UN FILTRO PASABANDA DIGITAL PARA SELECCIONAR AL MENOS DOS BANDAS DE FRECUENCIA; Y (D) ANALIZAR LOS DATOS DE LAS BANDAS MEDIANTE UNA TECICA ESTADISTICA MULTIVARIANTE PARA OBTENER EL VALOR DE LA PROPIEDAD. EL METODO ES PARTICULARMENTE UTIL PARA DETERMINAR LA DISTRIBUCION POR TAMAÑO DE LAS PARTICULOS DEL MATERIAL QUE SE HA MOLIDO EN UN MOLINO DE BOLAS.
