Introduction
For laboratories analyzing fine powders, advanced ceramics, battery materials, or pharmaceutical micronized particles, the Sonic Sieve Shaker offers a high-efficiency solution for particle size analysis down to 5μm. Unlike conventional mechanical or electromagnetic sieve shakers that rely on mechanical vibration, the Sonic Sieve Shaker uses a unique vertical air column and sonic oscillation to achieve rapid and gentle sieving of extremely fine powders.
The Sonic Sieve Shaker is essential for quality control and R&D in lithium-ion battery materials (graphite, lithium iron phosphate, silicon anode powders), specialty chemicals, advanced ceramics, and pharmaceutical micronized APIs. It delivers particle size distribution data in just 3-5 minutes—significantly faster than traditional methods.
What sets this Sonic Sieve Shaker apart is its ability to process sub-sieve particles without the mechanical grinding or agglomeration issues common in other shakers. With adjustable sonic amplitude, digital timer control, and compatibility with standard 200mm and 75mm test sieves, the Sonic Sieve Shaker delivers accurate, repeatable results for the most challenging fine powder applications.
Types of Sonic Sieve Shakers
Sonic sieve shakers are specialized for fine powder analysis. Common configurations include:
Standard Sonic Sieve Shakers–For general fine powder analysis (5μm–20mm)
High-Amplitude Sonic Sieve Shakers–For cohesive or sticky materials
Auto-Sonic Sieve Shakers–With automated amplitude adjustment
Portable Sonic Sieve Shakers – For on-site laboratory use
Our Sonic Sieve Shaker combines high-frequency sonic oscillation with adjustable amplitude, making it ideal for the most challenging fine powder applications—from battery materials to advanced ceramics.
Features
High-Frequency Sonic Oscillation
The Sonic Sieve Shaker generates a vertical air column oscillating at 50-60 Hz, creating a sonic wave that lifts and separates particles. This gentle action is ideal for fragile or cohesive materials that would be degraded by mechanical shakers.
Fine Particle Capability
Capable of analyzing particles as small as 5μm, the Sonic Sieve Shaker delivers accurate particle size distribution for sub-sieve materials that are impossible to separate with standard vibration methods.
Fast Processing Time
The Sonic Sieve Shaker completes most analyses in just 3 to 5 minutes—up to 5 times faster than conventional mechanical or electromagnetic shakers.
Adjustable Amplitude
Continuously adjustable sonic intensity allows operators to optimize screening action for different material types. Fragile particles benefit from lower settings; cohesive materials require higher amplitude.
Digital Timer Control
Set precise test durations from 1 to 99 minutes. Supports interval and continuous operation modes for fully automated testing cycles.
Versatile Sieve Compatibility
Compatible with standard 200mm (8-inch) and 75mm (3-inch) test sieves, with optional sizes available upon request.
Low Maintenance Design
No mechanical drive components—no belts, gears, or bearings. Annual maintenance costs are estimated at 70-80% lower than mechanical equivalents.
Compact Benchtop Design
Occupies minimal bench space in crowded laboratories. Acoustic enclosure minimizes operational noise for a quieter working environment.

The Sonic Sieve Shaker is engineered for fine powder analysis in R&D and quality control laboratories. The 200mm configuration is ideal for standard sample volumes of 50–200g, while the 75mm configuration is designed for micro-samples down to 5g—essential for precious or limited materials like lithium battery compounds or high-value APIs where sample conservation is critical.
Working Principle
The Sonic Sieve Shaker uses a unique sonic oscillation mechanism to achieve particle separation—with no moving mechanical parts in the sieve stack.
Step 1: Sonic Generation – An electronic oscillator drives a sonic transducer beneath the sieve stack, converting electrical energy into mechanical sonic waves at 50-60 Hz.
Step 2: Air Column Oscillation – The sonic waves create a vertical air column that oscillates beneath the sieve stack, applying a rhythmic lifting and dropping force to particles—similar to controlled tapping but without direct contact.
Step 3: Particle Fluidization – The sonic pulses lift particles off the sieve surface and suspend them in the air column. This fluidization effect prevents particles from clogging the mesh.
Step 4: Separation and Stratification – This continuous lift-drop cycle—repeated 50-60 times per second—rapidly separates particles by size. The Sonic Sieve Shaker achieves 95% of its final separation in the first 3 minutes, completing most analyses in 5 minutes or less.
