Mechanical Sieve Shaker

What is a mechanical sieve shaker?

Mechanical Sieve Shaker is used for particle size classification and sieving of granular and powdered materials. Its sieve mesh range can be flexibly adjusted according to the standard sieve configuration, with common mesh sizes covering 20 to 500 mesh (approximately 850 μm to 25 μm), depending on experimental requirements. It can be equipped with micron-level precision sieves to achieve finer particle size separation.

Mechanical sieve shakers allow for selection of appropriate equipment based on material properties. When sample sizes are minimal or only quick and simple particle size checks are required, test sieves are a reliable choice due to their operational flexibility. For easily agglomerated, statically charged, or high-precision fine powders, ultrasonic sieves are the best choice, as their high-frequency vibrations effectively deagglomerate and ensure sieving accuracy. When handling sticky particles that easily clog the screen, impact sieves effectively prevent sieve clogging through their combined rotational and impacting motions. For general-purpose particles, especially those with higher specific gravity or requiring a certain impact force, top-impact sieves offer efficient sieving through their up-and-down impact and horizontal rotational motions.

Types of Mechanical Sieve Shakers

Mechanical sieve shakers come in many types, and can be divided into four types according to the different structures of the equipment components: test sieves, tapping sieves, top-impact sieves, and ultrasonic sieves. The appropriate equipment can be selected according to the specific properties of the material being sieved.

The structure of mechanical sieve shaker

The Mechanical Sieve Shaker consists of a screen box, a vibrator, a support device, and a transmission system. The screen box contains a screen mesh, and the vibrator drives the screen box to generate high-frequency vibration, causing the material to separate into layers on the screen surface and completing particle size separation.

Screen frame: The screen frame is the main body of the test sieve, usually made of stainless steel or other corrosion-resistant materials. Screens with different apertures are provided on the screen frame.

Screen: The screen is the core component of screening and is made of stainless steel, brass and other materials. The aperture size of the screen determines the accuracy of the screening particle size.

Vibration device: A device that provides vibration force, which can be an electric vibrator, pneumatic vibrator, etc.

Clamping device: Used to stack and fix multiple screens.

Base: Supports the entire mechanical sieve shaker.

What is the principle of mechanical sieve shaker?

Mechanical sieve shakers utilize vibration, tapping, or impact to move materials on the sieve surface and separate them according to particle size; particles smaller than the sieve openings pass through the sieve, while larger particles remain on the sieve surface. Experimental sieve separators rely on motor vibration to move materials horizontally and vertically for grading; tapping sieves improve sieving efficiency through the combined action of vibration and an upper tapping device; top-impact sieves use upper and lower impacts to loosen and stratify materials, suitable for fine powder sieving; ultrasonic sieves superimpose high-frequency ultrasonic vibrations within the sieve mesh, causing fine particles to resonate, preventing clogging, and improving accuracy and speed.

Features of mechanical sieve shaker

Mechanical sieve shakers are compact and suitable for use in laboratory or small-scale production environments, facilitating movement and deployment. Their flexibility allows users to easily change sieves of different aperture sizes to meet specific screening needs, enabling precise classification and testing of materials of various particle sizes. The machine's simple and intuitive design allows even non-professionals to quickly learn how to use it. Its components are easy to disassemble, clean, and maintain, reducing operating costs. To improve screening efficiency, mechanical sieves are typically equipped with vibrators or oscillation devices. High-frequency micro-amplitude vibration effectively promotes particle separation and passage through the sieve, preventing clogging.

What is the use of mechanical sieve shaker?

Mechanical sieve shakers are used for particle size analysis, grading, impurity removal, and filtration of materials, playing a crucial role in sample preparation and material pretreatment. They separate particles of different sizes, remove impurities, and ensure uniform and pure materials, providing accurate and reliable basic data and high-quality raw materials for subsequent production and testing.

Particle size analysis: Through sieves with different apertures, the content of particles of different particle sizes in the material can be accurately determined, so as to obtain the particle size distribution curve of the material. In the production process, particle size analysis can be used to control the quality of the product and ensure the uniformity and stability of the product. According to the results of particle size analysis, the production process parameters can be optimized to improve product quality and production efficiency.

Sieving and grading: Separate particles of different particle sizes in the mixed material to obtain products of different specifications. For example, in the pharmaceutical industry, drug powders can be graded by particle size to meet different formulation requirements.

Sample preparation: Remove large particles or impurities in the sample to provide pure samples for subsequent analytical tests.

Quality control: Through sieving analysis, the quality of the product can be controlled to ensure that the product meets the specified quality standards.
