The sieve shaker method can determine the size of solid particles ranging from 125mm to 20μm.
This method is particularly effective for granular and powdery materials.
It is widely used in various industries to assess the particle size distribution.
5 Key Points About the Sieve Shaker Method
1. Size Range of Particles
The sieve shaker can measure the size of solid particles from as large as 125mm down to as small as 20μm.
This broad range allows for the analysis of a wide variety of materials, from relatively large grains to very fine powders.
2. Types of Materials
Sieve shakers are used in industries such as medicine, metallurgy, abrasives, chemical industry, pharmacopoeia, geology, and more.
These industries require precise measurements of particle size for quality control and to ensure the effectiveness of their products.
For example, in the pharmaceutical industry, particle size can affect the rate of dissolution of a drug, which in turn affects its efficacy.
3. Methodology
The sieve shaker operates by passing a sample through a series of sieves with progressively smaller mesh sizes.
The largest mesh sieve is placed at the top, and the smallest at the bottom.
As the sample is agitated, particles of different sizes are separated into different sieves based on their ability to pass through the mesh.
This process is known as sieve analysis or gradation test.
4. Accuracy and Reproducibility
Sieve analysis is favored for its accuracy and reproducibility.
It is a straightforward method that requires minimal investment and can provide results in a short time.
However, for very fine particles (smaller than 50 microns), additional techniques such as ultrasonic agitation or vacuum sieving may be required to ensure effective separation.
5. Applications of Different Sieve Shakers
There are various types of sieve shakers, including electromagnetic, Rotap, ultrasonic test, and DH-300T sieve shaker machines.
Each type may have specific applications or advantages depending on the material being tested and the required level of precision.
