Method and device for operating an air jet sieve for grain size analysis

摘要

The method has a slit jet rotated about a vertical central axis of the selected sieve beneath the sieve base (6) and supplied with air, which is extracted at a regulated suction pressure, according to the mesh size of the sieve, the sample material characteristics or the application field of the sample material. An independent claim is also included for an air jet sifting device.
