Laboratory sieve shaker

A Laboratory Sieve Shaker is used to separate and classify powders, granules, and other particulate materials according to particle size. By applying controlled mechanical movement to a stack of test sieves, it supports particle size analysis, quality control, research, and routine material testing.

The right configuration depends on sieve diameter, number of layers, mesh or aperture, sample quantity, material characteristics, and testing requirements.

Laboratory Sieve Shaker Specifications

The following specifications should be confirmed according to the selected configuration and testing application.

Sieve diameter affects the available screening area and practical sample loading. The number of layers determines how many particle size fractions can be separated in one test. Mesh or aperture should be selected according to the target size range and applicable test procedure.

Voltage, power, timing, sieve combination, and sample capacity should be confirmed for the selected model before ordering.

What Is a Laboratory Sieve Shaker?

A Laboratory Sieve Shaker is a mechanical screening instrument designed to separate particles according to size. A sample is placed on the upper sieve of a stacked series of test sieves, with smaller apertures normally arranged below.

During operation, controlled movement causes particles to travel across the mesh. Smaller particles pass through suitable openings while larger particles remain on the corresponding sieve. The retained fractions can then be weighed or evaluated to determine particle size distribution.

How Does a Laboratory Sieve Shaker Work?

The screening process generally includes four steps.

Sample Preparation

Prepare the material according to the selected test procedure and use a sample quantity suitable for the sieve diameter and equipment.

Sieve Selection

Choose test sieves that cover the required particle size range and arrange them from larger to smaller apertures.

Mechanical Screening

Place the sample on the upper sieve, secure the stack, and operate the shaker for the required screening period. Mechanical movement promotes separation as the sample passes across the mesh surfaces.

Result Analysis

After screening, the material retained on each sieve can be weighed and compared to determine the distribution of particle size fractions.

Moisture, agglomeration, static effects, sample loading, aperture size, and screening time can affect results. Consistent sample preparation and testing conditions are therefore important.

Applications

Laboratory Sieve Shakers are used for particle size analysis, particle classification, quality control, research and development, and routine material testing.

Typical materials include powders, granules, soil, minerals, chemicals, food materials, agricultural materials, and suitable pharmaceutical raw materials.

Test Sieve Compatibility

Test sieves are an essential part of the screening system. Sieve diameter determines the available screening area, while aperture determines which particles can pass through the mesh. A typical sieve stack uses larger openings at the top and progressively smaller openings below.

When selecting test sieves, consider sieve diameter, aperture or mesh, sieve material, and the applicable testing procedure. For standard-based testing, sieve dimensions and apertures should match the requirements of the applicable method.

Mesh and Particle Size Reference

The following table provides a reference for commonly used 200 mm test sieves.

Laboratory Sieve Shaker Types

Different screening requirements may call for different operating methods.

Standard Mechanical Configuration

Suitable for routine particle size analysis and general screening where the sample can pass through the selected mesh without severe blockage.

Electromagnetic Configuration

Uses electromagnetic excitation to generate controlled screening movement and can be considered when a different vibration method is required.

Ultrasonic Configuration

Adds ultrasonic energy to the screening process and can be considered for fine powders or fine meshes where particles tend to remain on the mesh or cause blockage.

The appropriate configuration depends on material properties, particle size, sieve aperture, sample quantity, and the required screening result.

How to Choose a Laboratory Sieve Shaker？

Start with the material being tested and identify the target particle size range.

Next, select suitable sieve apertures and match the sieve diameter to the expected sample quantity. The number of layers should correspond to the number of particle size fractions required in one test.

Sample loading should also be considered. Overloading a sieve can reduce particle movement and affect separation.

For fine powders or materials that tend to block the mesh, an ultrasonic configuration may be considered. For routine general-purpose testing, a conventional mechanical configuration may be sufficient.
