Standard Test Sieve

DECENT standard test sieves are essential equipment for particle size analysis in various industries. They provide accurate and reproducible results, adhering to strict mesh specifications. These sieves are widely used in laboratories for assessing particle size distribution and quality in fields such as minerals, metallurgy, chemical engineering, pharmaceuticals, food, and environmental protection.

Professionally providing various types of standard test sieves, these instruments are extensively used in laboratories across multiple industries. They play a crucial role in measuring the particle size distribution and assessing the quality of granular materials. Standard test sieves offer numerous advantages and possess distinct structural features that make them reliable and efficient tools for particle size analysis.

Structural Features

Standard test sieves consist of a sieve frame, sieve mesh, cover, and base. The frame is typically made of stainless steel, ensuring corrosion resistance and stability. The sieve mesh, available in metal or textile options, adheres to national or international standards for aperture and specifications. This strict adherence guarantees consistent and comparable screening results.

Working Principle

Utilizing vibration or rotation, standard test sieves achieve stratification and screening of materials on the sieve surface. Larger particles are retained on the sieve, while smaller particles pass through and collect in subsequent layers or containers. By weighing or counting the residual material on each sieve layer, the particle size distribution of the material can be determined.

Application Scope

Standard test sieves find applications in screening various granular materials, including ores, fertilizers, pigments, and powdered drugs. They are also useful for liquid-solid separation, such as sludge filtration and removal of suspended particles.

Operating Method

To operate a standard test sieve, evenly distribute the material on the sieve surface and stack the sieves in order of increasing sieve opening. Assemble the cover and base, place the sieves in the screening instrument, set the vibration or rotation parameters, and initiate the screening process. After completion, collect the material from each sieve layer and weigh or count it to obtain particle size distribution data.

Advantages

Standard test sieves offer easy operation, ensuring accurate and reproducible results. The strict adherence to standardized sieve mesh specifications enables consistency and comparability between different laboratories. These sieves serve as essential tools for laboratory particle size analysis, supporting quality control and research efforts in various industries.
