Laboratory sieve mesh sizes range from 4 mesh (4.75 mm) to 500 mesh (0.025 mm) for standard applications, with special sieves capable of measuring down to 3 micrometers. The choice of mesh size depends on the specific application and the size range of the particles being measured.
Detailed Explanation:
-
Standard Mesh Sizes:
- Common Sizes: Laboratory test sieves typically come in various diameters, including 3" (75 mm), 8" (200 mm), 12" (300 mm), 18" (500 mm), and 24" (600 mm). The mesh sizes for these sieves range from 4 mesh (4.75 mm) to 500 mesh (0.025 mm). This range allows for the sieving of particles across a broad spectrum, from relatively large to very fine particles.
-
Specialized Sieves:
- Fine Mesh Sizes: For applications requiring the measurement of extremely fine particles, sieves with mesh sizes smaller than 20 μm are available. These are often referred to as "electroformed" or "micromesh" sieves and can have openings as fine as 3 micrometers. These sieves are crucial for industries dealing with very fine particulate matter, such as pharmaceuticals or nanomaterials.
-
Application-Specific Sieves:
- Selection Criteria: The choice of sieve mesh size is determined by the specific needs of the analysis. Larger mesh sizes are used for coarser materials, while smaller mesh sizes are necessary for finer materials. This selection is guided by both industry standards and the specific requirements of the material being tested.
-
Standards and Specifications:
- ASTM and ISO Standards: The ASTM E11 and ISO 3310-1 standards provide specifications for woven wire sieves, covering particles from 150 mm (6 in) to 5 µm (0.0002 in). These standards ensure that the sieves are manufactured and used in a manner that guarantees accurate and reliable results.
-
Technological Advancements:
- Modern Sieving Techniques: While the basic technology of sieving has not changed significantly since the 1940s, modern techniques have improved the precision and efficiency of sieve analysis. For instance, "micro" sieving down to 5 μm is now possible using special techniques, enhancing the capability to analyze very fine particles.
In summary, laboratory sieve mesh sizes are highly variable, ranging from coarse 4 mesh to ultra-fine 500 mesh and beyond, depending on the specific requirements of the material being tested and the standards set by international and national regulatory bodies.
