Description

AZA 0923 G.I. Frame Sieves: Robust & Reliable for Large-Scale Particle Analysis by Azalab

The Azalab AZA 0923 G.I. Frame Sieves are heavy-duty, high-performance test sieves specifically designed for the demanding requirements of particle size distribution analysis of coarse aggregates, soils, and other bulk materials. Available in larger standard diameters of 300 mm and 450 mm, these sieves feature galvanized iron (G.I.) frames that are further enhanced with a durable powder coating. This combination ensures superior strength, excellent corrosion resistance, and longevity, making them an ideal choice for civil engineering, construction, mining, and quality control laboratories across India where robust and cost-effective sieving solutions are crucial.

The Strength of G.I. Frames with AZA 0923 G.I. Frame Sieves

While brass frames are common for smaller sieves, larger diameter sieves, especially those used for bulk materials like aggregates, require exceptional rigidity and durability. This is where the galvanized iron frame of the AZA 0923 G.I. Frame Sieves excels:

• Galvanized Iron (G.I.) Frame: The core frame is made of steel, which is then hot-dip galvanized. This process applies a protective zinc coating that acts as a sacrificial layer, providing excellent resistance against rust and corrosion, even in humid or harsh environments often encountered in construction sites and material handling.
• Powder Coated Finish: Adding an extra layer of protection, the G.I. frame is meticulously powder coated. This involves applying a dry powder (a type of plastic or resin) electrostatically and then curing it under heat. The result is a tough, durable, and aesthetically pleasing finish that offers:
  • Enhanced Corrosion Resistance: An additional barrier against moisture and chemicals.
  • Superior Scratch & Abrasion Resistance: Protects against wear and tear during handling and vigorous shaking.
  • Improved Aesthetics: A smooth, uniform, and attractive finish.
• Inherent Strength & Rigidity: G.I. frames provide significantly higher structural integrity and rigidity compared to brass frames of similar dimensions, making them less prone to deformation under heavy loads or during intensive mechanical sieving. This ensures the precise geometry of the sieve remains consistent over time.

These features make the AZA 0923 sieves particularly well-suited for sieve analysis of coarse materials, ensuring reliable and repeatable results for quality control and material classification.

Key Features of the AZA 0923 G.I. Frame Sieves for Demanding Applications: Azalab’s AZA 0923 G.I. Frame Sieves are engineered for performance, longevity, and compliance:

• Robust Galvanized Iron Frame: Provides superior structural strength, durability, and inherent corrosion resistance for heavy-duty applications.
• Durable Powder Coating: Offers enhanced protection against environmental factors, abrasion, and chemicals, extending the sieve’s lifespan and maintaining its appearance.
• Standard Large Diameters: Specifically available in:
  • 300 mm (12-inch) diameter: Ideal for larger sample sizes, commonly used for aggregates and bulk materials.
  • 450 mm (18-inch) diameter: Suitable for very large samples or when a wider sieving surface area is preferred, often for field labs or high-volume testing.
• Precision Woven Mesh: The sieving media consists of high-quality stainless steel or phosphor bronze woven wire cloth. This mesh is manufactured to stringent aperture tolerances as per international standards (e.g., IS 460, ASTM E11, ISO 3310-1), ensuring accurate and consistent particle separation.
• Wide Range of Aperture Sizes: Available in a comprehensive range of mesh openings, from coarse sizes (e.g., 100 mm, 75 mm, 63 mm, etc.) down to finer sizes (e.g., 4.75 mm, 2.36 mm, 1.18 mm, etc.), catering to all aggregate and soil gradation requirements.
• Seamless Construction: Frames feature smooth, seamless construction to prevent material entrapment in crevices, facilitating easy cleaning and minimizing cross-contamination.
• Stackable Design: Engineered to stack perfectly and securely with other sieves of the same diameter, enabling efficient multi-sieve analysis, whether used manually or with large-capacity sieve shakers.
• Individual Identification: Each sieve is clearly marked with its nominal aperture size and a unique serial number for full traceability.
