Vibro Sifter Screen in 316L Stainless Steel (AISI 316L (1.4404)) is used for grading and de-lumping powders and granules on round vibratory sifters with tensioned stainless mesh screens in sanitary gasketed frames. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L Stainless Steel Vibro Sifter Screen Is Used
- Pharmaceutical: granule sizing before tableting and capsule filling.
- Food & dairy: sifting flour, sugar, milk powder and spices.
- Chemicals & pigments: scalping and safety screening of powders.
- Plastics & ceramics: resin and glaze sieving.
Ordering Vibro Sifter Screen in 316L Stainless Steel
- Machine size: 20, 30, 36 or 48 in frame matched to the sifter make.
- Mesh: 10–200 mesh; 316L cloth with a test certificate for GMP batches.
- Frame & seal: Gasketed SS316L ring or tension ring, with silicone or EPDM gasket.
Mistakes to Avoid with Vibro Sifter Screen
- Running a torn screen, which lets oversize or metal fragments into product.
- Using an un-certified cloth where the GMP file demands a mesh certificate.
