Laboratory powder sifter, also known as a laboratory sieve shaker or powder sieve, is a specialized piece of equipment used in research laboratories, quality control labs, and production facilities to perform particle size analysis and quality testing of powdered materials. This equipment is essential for ensuring the consistency and quality of powders used in various industries, including pharmaceuticals, food processing, chemicals, and cosmetics.

Laboratory powder sifter Working principle

The laboratory powder sifter uses vibration and other methods to make the material subject to vibration force on the screen. Particles larger than the screen aperture are retained on the screen, and particles smaller than the screen aperture pass through the screen and fall into the next layer of the screen, thereby achieving material grading. By adjusting the vibration frequency, amplitude and screen specifications, the particles can be graded.

Laboratory powder sifter Structure and Components

Sieve Stack: The laboratory powder sifter consists of a stack of sieves with varying mesh sizes that are used to separate particles based on their size.

Sieve Shaker: The equipment is equipped with a sieve shaker mechanism that applies mechanical vibrations to the sieve stack, facilitating the separation of particles.

Drive Unit: The drive unit provides the necessary power to operate the sieve shaker, typically using an electric motor or other power source.

Control Panel: A control panel allows operators to adjust the vibration intensity, duration, and other parameters for optimal particle size analysis.

Sieve Cover: Some models may include a cover to prevent dust and particles from escaping during the sieving process.

Support Frame: The sieve stack is housed within a support frame that provides stability and support during operation.

Laboratory powder sifters are widely used in many fields

Chemical laboratory: used for screening of granular raw materials and grading of granular materials, and studying the particle characteristics and particle size distribution of various powder raw materials.

Food science laboratory: used for screening and classification of food particles, food component analysis and particle characteristics research.

Pharmaceutical laboratory: used for screening of drug powders and particle characteristics research, helping to optimize drug formulations and preparation processes.

‌Material Science Laboratory‌: Used for screening and analyzing material particles and studying the particle size characteristics of materials‌.

The laboratory powder sifter is a valuable tool in laboratories and production facilities for conducting particle size analysis and quality testing of powdered materials. Its efficiency, accuracy, and versatility make it an indispensable instrument for ensuring the quality and consistency of powders used in various industries.
