Test Sieves

Test sieves are precision instruments used in various industries and laboratory settings to determine the particle size distribution of granular materials. These sieves consist of a woven wire mesh screen stretched over a circular frame, typically made of stainless steel or brass. They are widely employed in quality control, research, and development processes across industries such as pharmaceuticals, food and beverage, chemicals, construction, and environmental testing.

The primary function of test sieves is to separate particles based on their size. This is achieved by passing a sample through a series of stacked sieves with progressively finer mesh sizes. The particles smaller than the mesh openings pass through the sieve, while larger particles are retained on top. Each sieve is labeled with its mesh size, allowing for precise classification of particle sizes.

Test sieves are available in a wide range of mesh sizes, from coarse to fine, to accommodate different materials and desired particle size ranges. They are manufactured to strict quality standards to ensure accuracy and reliability in particle size analysis.

Key features of test sieves include:

1. High-quality construction: Test sieves are constructed from durable materials such as stainless steel or brass to withstand repeated use and maintain accuracy over time.

2. Precise mesh openings: The mesh openings are precisely woven to accurate tolerances, ensuring consistent and reproducible results.

3. Compatibility: Test sieves are designed to be compatible with various types of sieve shakers and testing equipment commonly used in laboratories.

4. Traceability: Many test sieves come with certification documents that provide traceability and assurance of quality, making them suitable for use in regulated industries.

5. Versatility: Test sieves can be used for a wide range of applications, including determining particle size distribution, quality control, and research and development.

Overall, test sieves are essential tools for characterizing particle size distribution and are widely used in laboratories and industries where accurate particle analysis is critical.
