Abstract

Procedimiento operativo para dispositivo de cribado de chorro de aire para análisis de partículas. El procedimiento tiene un orificio de salida del chorro que gira alrededor de un eje vertical central de la criba seleccionada debajo de la base de la criba (6) y suministrada con aire que se extrae a una presión de succión regulada, de acuerdo con el tamaño de la malla de la criba, las características del material de la muestra o el campo de aplicación del material. Se incluye una reivindicación independiente para un dispositivo de criba de chorro de aire.
