Test Sieve Shaker

A Test Sieve Shaker is a laboratory screening machine used for particle size analysis, material classification, and quality control. It separates powders, granules, and other particulate materials through controlled mechanical vibration of a stack of test sieves.

Different sieve diameters, mesh sizes, and numbers of sieve layers can be selected according to the material and testing requirements. It is suitable for laboratory testing, research, quality control, and routine particle size evaluation.

Test Sieve Shaker for Particle Size Analysis

A Test Sieve Shaker provides a controlled method for determining particle size distribution. A series of test sieves with progressively smaller apertures is arranged from coarse to fine, and the sample is placed on the upper sieve.

During operation, vibration moves the material across the sieve surfaces. Smaller particles pass through the corresponding apertures, while larger particles remain on the upper sieves. The material retained on each sieve can then be collected and weighed to determine different particle size fractions.

This makes the equipment suitable for raw material inspection, finished product testing, batch comparison, and laboratory quality control.

Test Sieve Shaker Specifications

Actual frequency, amplitude, power, dimensions, and sample capacity depend on the selected configuration. The final specification should be matched to the intended testing procedure.

The configuration should be selected according to sieve diameter, required particle size range, sample quantity, and testing method.

Parameter	Typical Configuration
Sieve Diameter	75, 100, 200, 300 mm and other options
Sieve Layers	1–8 layers
Mesh Size	Selected according to required aperture
Sieve Material	Stainless steel or customized material
Vibration Frequency	According to selected configuration
Amplitude	According to selected configuration
Timer	Adjustable
Power Supply	According to selected configuration
Main Application	Particle size analysis and laboratory screening

Compatible Test Sieves and Accessories

The shaker can be configured with compatible test sieves, covers, receiving pans, and related components.

Sieve diameter, aperture, mesh material, and number of layers can be selected according to the required particle size range. A typical sieve stack consists of several test sieves, a cover, and a receiving pan.

Sieve Diameter, Mesh and Layer Options

Sieve diameter affects the available screening surface and suitable sample quantity. Common laboratory options include 75, 100, 200, and 300 mm.Sieve layers determine how many particle size fractions can be separated during one test. Configurations from 1 to 8 layers can be selected according to the testing requirement.

Mesh and aperture determine the particle size that can pass through each sieve. Select the mesh according to the target particle size and required aperture.

Mesh	Approx. Aperture
20 Mesh	0.90 mm
40 Mesh	0.45 mm
60 Mesh	0.30 mm
80 Mesh	0.18 mm
100 Mesh	0.15 mm
200 Mesh	0.075 mm
325 Mesh	0.045 mm
500 Mesh	0.030 mm

For applications requiring a specific aperture or test sieve standard, the sieve configuration should be matched to the required testing range.

How Does a Test Sieve Shaker Work?

The sample is placed into the upper sieve of a secured sieve stack. Controlled mechanical vibration distributes the material across the sieve surfaces and promotes separation according to particle size.Particles smaller than the sieve aperture pass through to the lower sieves, while larger particles remain above it. After the selected screening period, the retained material can be collected for weighing and analysis.

Consistent sieve specifications, sample quantity, screening time, and operating conditions help improve the comparability of test results.

Test Sieve Shaker Testing Process

A typical laboratory screening test follows six basic steps.

Select the test sieves. Choose the sieve diameter and aperture range according to the required particle size analysis.

Arrange the sieve stack. Place the sieves from coarse to fine above the receiving pan.

Load the sample. Use a representative sample suitable for the selected sieve configuration.

Secure and set the shaker. Fix the sieve stack and select the required screening time.

Start the test. Controlled vibration separates the material according to particle size.

Collect and analyze the fractions. Weigh the material retained on each sieve and calculate the particle size distribution.

The exact procedure should follow the applicable laboratory standard or internal quality control method.

Particle Size Analysis Results

Sieve testing provides the mass retained on each sieve, percentage retained, particle size fractions, and overall particle size distribution.

A basic calculation is:

Percentage Retained = Mass Retained on Sieve ÷ Total Sample Mass × 100

The results can be used to compare particle size distribution between different samples or production batches.

Applications

The equipment can be used for laboratory testing of powders, granules, and other particulate materials.

Food and agriculture: flour, starch, sugar, grains, spices, and other particulate ingredients.

Pharmaceutical: powders, granules, and excipients.

Chemical: pigments, catalysts, mineral powders, and granular materials.

Mineral and construction: sand, aggregates, and mineral powders.

Quality control and research: raw material inspection, batch comparison, particle size testing, and product consistency evaluation.

How to Choose a Test Sieve Shaker

The correct configuration should be based on the testing requirement.

Sieve diameter: Match the diameter to the sample quantity and required screening area.

Particle size range: Select the mesh and aperture according to the target particle size.

Number of layers: Choose the number of sieves according to the required particle size fractions.

Sample quantity: Ensure the sample amount is suitable for the selected sieve configuration.

Sieve material: Select stainless steel or another suitable material according to the application.

Testing requirements: Confirm screening time, vibration settings, sieve specifications, and power requirements.

For configuration assistance, provide the material type, target particle size, sample quantity, preferred sieve diameter, and required number of layers.

Test Sieve Shaker vs Industrial Vibrating Sieve

Although both use vibration for material separation, their primary applications are different.

Feature	Test Sieve Shaker	Industrial Vibrating Sieve
Main Purpose	Particle size analysis	Production screening
Environment	Laboratory	Production line
Operation	Batch testing	Continuous screening
Sample Quantity	Controlled samples	Medium to large quantities
Main Goal	Determine particle size distribution	Separate and classify materials
Typical Application	Quality control and research	Industrial processing

A laboratory shaker is appropriate for controlled particle size testing, while an industrial vibrating sieve is generally selected for continuous screening and production processing.
