Precision SS316L Wire Mesh Sieves for Accurate Particle Classification

Skytech Ultrafab SS316 Vibro Sifter Sieves are precision-woven stainless steel wire mesh screens fabricated from SS 316L for use in vibratory sifters and gyro screens across pharmaceutical, food, chemical, and mineral processing industries. With aperture sizes from 20 µm to 25 mm and frame diameters from 400 mm to 1500 mm, every sieve is manufactured to exact OEM dimensions and supplied with a wire mesh conformance certificate for regulated industry applications.

What Are Vibro Sifter Sieves?

Vibro Sifter Sieves are circular wire mesh screens clamped into the frame of a vibratory (gyratory) sifter machine. As the machine vibrates, material fed onto the sieve surface is separated by size — particles smaller than the mesh aperture pass through and are collected as the product fraction, while oversize particles are retained on the screen surface and discharged separately. The wire mesh specification — aperture size, wire diameter, weave type — directly determines the classification efficiency and throughput of the sifter.

Features and Benefits

• SS 316L Wire Mesh: All sieves woven from SS 316L wire for maximum corrosion resistance against acidic, alkaline, and chloride-containing process materials in pharmaceutical and chemical sifting
• Precision Aperture Control: Woven apertures from 20 µm to 25 mm with tight dimensional tolerance — consistent aperture size across the full screen area for accurate, repeatable particle classification
• Clamping Ring Frame: Screen mounted in a precision-machined SS 316L clamping ring with rubber gasket seal — fits directly into all standard vibratory sifter frames without modification
• Multiple Weave Types: Plain weave for maximum open area and throughput; twill weave for finer apertures with increased wire strength; Dutch weave for very fine filtration applications
• Electropolished Option: EP finish on pharmaceutical-grade sieves reduces surface roughness, prevents product adhesion to wire surfaces, and simplifies cleaning validation between batches
• OEM Compatible: Frame diameter and clamping ring dimensions manufactured to fit Sweco, Kason, Russell Finex, Gansons, Shakti, and all other standard vibratory sifter brands

Technical Specifications

Applications

• Pharmaceutical Powder Sifting: De-lumping and classifying APIs, excipients, and granules before blending, tableting, or filling — critical for uniform tablet weight and dissolution performance
• Food Ingredient Classification: Sizing of flour, sugar, starch, spices, and food additives to remove oversize agglomerates and ensure uniform particle size in food manufacturing
• Chemical Powders: Classification of pigments, dyes, catalysts, and specialty chemical powders for consistent particle size distribution in end products
• Mineral Processing: Wet and dry screening of fine minerals, calcium carbonate, silica, and talc at the coarser end of the vibro sifter aperture range
• Plastics & Rubber: Classifying polymer pellets, rubber compounds, and plastic powders to remove fines and oversize particles before compounding and moulding
