20cm Test sieve

What is 20cm Test Sieve?

A 20cm Test Sieve is a type of laboratory equipment used for particle size analysis. It is made up of a woven wire mesh with precise openings or slots that allow particles of certain sizes to pass through while retaining larger particles. The test sieves come in different sizes, typically ranging from 3-18 inches in diameter. The 20cm test sieve is one of the most commonly used sizes, providing efficient separation of particles in granular or powdered substances. They are widely used in industries such as agriculture, construction, mining, and environmental testing to ensure consistency in particle sizes for quality control and product development.

What size is a 20cm Test Sieve?

A 20cm test sieve refers to the diameter of the frame of the sieve, which is 20 centimeters or approximately 7.9 inches. This size is commonly used in laboratory testing to separate and classify particles based on their size. The mesh size of the sieve, which is the number of openings per inch, can vary depending on the specific application, ranging from a few microns to several millimeters. The 20cm test sieve is a standard size and is widely available in various materials such as brass, stainless steel, or plastic.

What industry is the 20cm Test Sieve used in?

The 20cm Test Sieve is mainly used in the laboratory field, and is widely used in materials engineering, chemical industry, medicine, food, mining, metallurgy, environmental protection and other industries. The specific application areas are as follows:

1. Materials Engineering: It is used to analyze the physical and mechanical properties of metals, ceramics, polymers and other materials.

2. Chemical industry: used for the screening of catalysts in chemical reactions such as preparation of catalysts and adsorbents.

3. Medicine: It is used in the screening of medicinal materials and powders in pharmaceuticals.

4. Food: used for screening food raw materials (such as starch, fat, protein, etc.) in the process of food manufacturing.

5. Mining and metallurgy: used for screening metal ore, powder, alloy, steel and other materials in the ore and metallurgical industry.

6. Environmental protection: It is used in the field of environmental protection to screen particulate matter and microorganisms in waste water and waste gas.

Applied materials include: powdery materials, such as mineral powder, cement, fly ash, starch, etc., granular materials, such as coal, sand, grain, etc., and liquid materials, such as chemical reagents, pigments, etc.

What are the Advantages of 20cm Test Sieve?

1. Larger surface area: A 20cm Test Sieve has a larger surface area compared to smaller sized sieves, allowing for more efficient sieving in a shorter period of time.

2. High accuracy: made to a higher standard, which translates to higher accuracy and more consistent results when analyzing samples.

3. Durable: made from high-quality materials such as stainless steel, ensuring they can withstand heavy usage in industrial settings without deformation or damage.

4. Versatile: can filter out the finest particles, making them suitable for use in a wide range of applications such as pharmaceuticals, food testing, and mineralogy.
