Ultrasonic Vibrating Sieve Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for sieving fine and electrostatic powders on vibratory sifters with a stainless mesh screen driven by an ultrasonic transducer ring that stops blinding. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Ultrasonic Vibrating Sieve Screen Is Used
- Metal powders & additive manufacturing: sieving titanium, nickel and stainless powders at 15–60 µm.
- Battery materials: cathode and anode powder screening.
- Pharmaceutical & nutraceutical: fine API and excipient sieving.
- Pigments & toners: fine powder classification.
Ordering Ultrasonic Vibrating Sieve Screen in 304 Stainless Steel
- Frame size: Match the sifter diameter (600–1500 mm).
- Mesh: 200–500 mesh; ultrasonic drive becomes essential below about 100 µm.
- Transducer & cable: Ring transducer frequency and generator compatibility.
Mistakes to Avoid with Ultrasonic Vibrating Sieve Screen
- Running ultrasonics on slack cloth, which tears it.
- Mixing generator and transducer from different makers.
