Laboratory standard test sieve

What is a Laboratory standard test sieve?

Laboratory standard test sieve is a tool used to screen and grade granular and powdered materials to determine their particle size distribution. It consists of a sieve with a standard aperture and a sieve frame. The sieve frame is usually round or square, and the sieve is made of stainless steel, brass and other materials.

How does Laboratory standard test sieve work?

The sample to be tested is evenly spread on the sieve, and particles smaller than the sieve holes are allowed to pass through the sieve through vibration or sieving, while particles larger than the sieve holes are retained on the sieve. Through multiple sieving, particle components of different particle sizes can be obtained, thereby determining the particle size distribution of the sample.

What types of Laboratory standard test sieves are there?

Stainless steel screen: a screen woven from stainless steel wire

Features: strong corrosion resistance, high temperature resistance, high strength

Use: widely used in food, medicine, chemical industry, metallurgy and other industries, used to screen various materials, such as powder, particles, etc.

Brass screen: a screen woven from brass wire

Features: good thermal conductivity and wear resistance

Use: commonly used in food and medicine industries, as well as some occasions that require high thermal conductivity of the screen

Nylon screen: made of nylon material

Features: good elasticity and good chemical corrosion resistance

Use: usually used to screen materials with small particles or easily damaged, suitable for food and medicine industries, and screening some easily damaged materials.

Characteristics of Laboratory standard test sieves

1、Accuracy: With standardized mesh size, it provides accurate particle distribution data.

2、Durability: Made of wear-resistant and corrosion-resistant materials, it has a long service life.

3、Easy to clean and maintain: The metal screen frame and screen are easy to clean and maintain, ensuring the accuracy of the screening results.

4、Wide applicability: It is suitable for the analysis and screening of various granular materials and is widely used in different fields.

What are the uses of Laboratory standard test sieves?

Laboratory standard test sieves are used to determine the particle size distribution of granular materials, monitor the consistency and quality of product particle size during production, and study the characteristics and behavior of granular materials.

Structure and technical parameters of Laboratory standard test sieve

Laboratory standard test sieves usually consist of a sieve frame, a sieve, a bottom plate and a top cover. The sieve frame is the frame that supports the sieve. The sieve is the core component of the test sieve. The bottom plate is located below the sieve to collect the material passing through the sieve.
