Abstract

EL INVENTO SE TRATA DE UN DISPOSITIVO PARA LA PREPARACION DE PRUEBAS, O SEA, DETERMINACION DE TAMAÑOS INDICADORES REPRESENTATIVOS, QUIMICOS Y/O FISICOS DE MATERIAL PROBADO, QUE SE EXTRAE EN FORMA DE UNA MEZCLA DE PARTICULAS DE POLVO FINAS O BASTAS SOBRE UNA TUBERIA DE ASPIRACION (40) DE UNA CORRIENTE DE MATERIAL A GRANEL. EL DISPOSITIVO ESTA EQUIPADO CON UNA PRIMERA CRIBA HUECA (56) DISPUESTA DENTRO DE UNA PRIMERA CAJA (44), POSICIONADA EN DISTANCIA DE LA CORRIENTE DE MATERIAL A GRANEL Y EN DISTANCIA DE LA ABERTURA DE ASPIRACION (90) DE LA TUBERIA DE ASPIRACION (40), Y CON UNA SEGUNDA CRIBA HUECA (86) DISPUESTA DENTRO DE UNA SEGUNDA CAJA (68), QUE ADEMAS DE LA SEGUNDA CRIBA HUECA (68) ESTA UNIDA CON UNA FUERTE PRESION NEGATIVA (42). LO ULTIMO SIRVE PARA TRANSPORTAR LAS PARTICULAS DE POLVO A TRAVES DE AMBAS CAJAS, HASTA QUE ADMITA ESTO EL TAMAÑO INDICADOR DE LAS PARTICULAS DE POLVO, A TRAVES DE AMBAS CRIBAS HUECAS.
