Brass Test Sieves

Product Description:

SV Technocrats India’s Brass test sieves are essential laboratory tools used for particle size analysis of materials like soil, aggregates, sand, cement, and powders. They help in grading and separating particles based on size for construction, industrial, and scientific applications.

Components of Brass Test Sieves

1. Frame – Made of brass (sometimes stainless steel) for durability and corrosion resistance.

2. Mesh (Wire Cloth) – Typically made of brass or stainless steel with precise apertures for accurate particle separation.

3. Rim and Joint – Strongly welded or soldered to ensure rigidity and prevent deformation.

Description

Types of Brass Test Sieves

1. Coarse Sieves (4.75mm to 100mm) – Used for larger aggregates.

2. Fine Sieves (75µm to 4.75mm) – Used for sand, cement, and soil gradation.

3. Micro Sieves (Below 75µm) – Used in powder and chemical industries.
Common mesh sizes follow standards like IS:460, ASTM E11, and BS 410, with sizes ranging from 100mm (4 inches) to 38µm (No. 400 mesh).

Sieve Analysis Process

1. Stack the Sieves – Arrange sieves in descending order of size.

2. Weigh the Sample – A known weight of material is used.

3. Sieve Shaking – Manually or using a mechanical sieve shaker.

4. Weigh the Retained Particles – The amount of material left on each sieve is recorded.

5. Calculate Particle Distribution – Percentage of retained material is used for analysis.

Applications of Brass Test Sieves

• Construction Industry – Aggregate and sand grading for concrete mix design.

• Soil Testing – Classification in geotechnical engineering.

• Pharmaceutical & Food Industry – Powder consistency control.

• Mining & Metallurgy – Ore and mineral particle size analysis.
