Mechanical Sieve Shaker for Particle Size Analysis
The Mechanical Sieve Shaker is designed for laboratory particle size analysis and material classification using a stack of test sieves.
It combines circular shaking with vertical tapping to distribute particles across the sieve surface and separate different size fractions.
The equipment supports 200 mm and 300 mm test sieve configurations and provides a 0–99 minute timing range for controlled laboratory testing.
Key Features of the Mechanical Sieve Shaker
Dual Mechanical Sieving Motion
The machine combines circular movement with vertical tapping.
Circular movement distributes the sample across different areas of the mesh, while vertical tapping changes particle orientation and assists near-size particles in reaching suitable sieve openings.
The shaker provides approximately 221 shaking movements per minute and 147 vertical taps per minute.
200 mm and 300 mm Test Sieve Compatibility
The shaker supports 200 mm and 300 mm test sieve configurations.
Multiple Sieve Layers
Multiple test sieves can be stacked for simultaneous separation of several particle size fractions, with up to 7 sieve layers in the current configuration.
Adjustable Sieving Time
A 0–99 minute timer allows the operator to establish a consistent sieving duration for comparable laboratory tests.

How Does a Mechanical Sieve Shaker Work?
How Does a Mechanical Sieve Shaker Work?
The Mechanical Sieve Shaker uses a motor-driven transmission and eccentric mechanism to generate controlled movement of the sieve stack.
Circular Movement
The motor drives the eccentric mechanism, causing the sieve stack to move along a controlled circular path.
This distributes the sample across the mesh and helps reduce localized material buildup.
Vertical Tapping
A mechanical tapping mechanism produces repeated vertical impacts on the sieve stack.
This helps particles change orientation and assists particles close to the aperture size in reaching suitable openings.
Particle Separation
Smaller particles pass through the appropriate sieve openings while larger particles remain above the mesh.
When sieves with progressively smaller apertures are stacked together, several particle size fractions can be separated during one test.
