In particle size analysis and classification of particulate materials, laboratory test sieve is a fundamental tool frequently used. To accommodate different feed sizes in various experiments, this equipment offers various diameter specifications, including 100mm, 200mm, and 300mm; generally, larger diameter models can hold more samples.

Structurally, it consists of a sieve frame, sieve mesh, and base. The sieve frame is typically a round or square metal frame, and full-height or half-height models can be selected depending on the loading capacity. The sieve mesh is fixed to the frame, and its aperture size needs to be selected according to the specific standards of the experiment. The base serves to stabilize the entire structure. In practice, these sieves are often used in conjunction with vibrating equipment such as electromagnetic sieves or top-impact sieves.

 

Operation procedure of laboratory testing sieve

The use of test sieves can help researchers understand the particle size distribution and particle shape of granular materials. During the experiment, the material to be tested is first put into the sieve frame, and then the particles are sieved on the sieve through vibration or rotation. Larger particles will be blocked by the screen and stay in the upper layer, while smaller particles will fall into the lower layer through the screen. By weighing or counting particles at different levels, the particle size distribution of the particles can be obtained.

What is the purpose of laboratory test sieve?

Laboratory test sieves have applications across numerous fields. In materials research, they are used to observe material flow patterns, bulk density, and porosity. In soil science, by breaking down soil samples into particles of varying sizes, researchers can understand the soil's texture and composition, thereby inferring its physical properties and nutrient retention.

Moving into mineral development, in the beneficiation process, sieves help ore stratification by particle size, aiding in determining the mineral's origin and the distribution characteristics of the deposit. In chemical production, they are frequently used to control particle size, directly impacting the rate of subsequent reactions and the final product's performance. Furthermore, in medical research, they are commonly used in the preparation of biomaterials, assisting researchers in obtaining microparticles of different sizes for tissue engineering or other related carrier studies.

Precautions for laboratory testing sieve

In order to ensure the accuracy and reliability of the test sieve, you need to pay attention to the following points when using it. First of all, the selection of screen mesh should be determined based on experimental needs and the characteristics of the materials to be screened. Secondly, the vertical vibration or rotation of the screen frame should be maintained during the screening process to ensure that the particles are evenly distributed on the screen. In addition, in order to avoid clogging and improve screening efficiency, the condition of the screen needs to be cleaned and checked regularly. Finally, when using a test sieve for particle size analysis, the appropriate classification method should be selected according to the purpose of the experiment, such as wet sieving, dry sieving or air sieving.
