How Does Sieve Analysis Work?

A representative sample is placed on top of a stack of sieves arranged with decreasing aperture sizes from top to bottom. The shaker runs for a set time and amplitude. Each sieve fraction is weighed and the percentage particle size distribution is calculated.

⚡
Electromagnetic 3D Motion
Combined horizontal and vertical motion in three dimensions accelerates material transfer between sieves and delivers repeatable fractionation in short cycle times.
🎯
Amplitude and Time Control
Digital timer and adjustable amplitude ensure the same test conditions are applied every time. Closed-loop control is available for accredited laboratories requiring the highest repeatability.
💧
Dry and Wet Sieving
Standard dry sieving covers most applications. Wet sieving or air jet sieving (Air Sizer 200) is preferred for cohesive, electrostatic, or very fine powders where dry methods are unreliable.

Endecotts Air Sizer 200 Air Jet Sieve
Endecotts
Air Sizer 200

The Air Sizer 200 is an air jet sieve designed for single-fraction analysis of fine dry powders. Starting from 20 µm, it delivers the precision that vibration sieve shakers cannot achieve with electrostatic or cohesive materials. A rotating air stream disperses the sample, keeps mesh apertures clear, and produces reproducible results in minimal time.

EFL 300

EFL 300 is an electromagnetic vibratory sieve shaker designed for 300 mm sieves. Up to 6 full-height or 12 half-height sieves can be used at once. A digital timer and 10-step amplitude control deliver repeatable results for every sample type.

What You Wonder About

A representative sample is placed on top of a nest of sieves stacked with decreasing aperture sizes from top to bottom. The shaker runs for a defined time at a set amplitude. After sieving, the mass retained on each sieve is weighed on a precision balance. The results give the percentage particle size distribution, which is plotted as a distribution curve.

Dry sieving is the standard method for free-flowing powders — no preparation required. Wet sieving is used for cohesive or electrostatic materials, dispersing the sample in a liquid before sieving. Air jet sieving (Air Sizer 200) uses a rotating air flow to keep apertures clear, giving more reliable results on very fine powders than vibratory methods.

The key questions are: How much sample per run? What sieve diameter is required (200, 300 or 450 mm)? Is wet sieving needed? Is digital result logging required for accreditation? Are the materials electrostatic or very fine? Based on your answers we can select the right model together. Contact us for a technical consultation or demo.

The "CL" in Octagon 200CL stands for Closed-Loop. This system automatically maintains the set vibration amplitude to ±0.1 mm throughout the entire analysis. On the standard Octagon 200, amplitude is set manually. The 200CL also connects to SieveWare software via RS232 for digital data capture and reporting. It is the preferred choice for accredited laboratories and quality systems requiring full traceability.

ISO 3310 defines the dimensional tolerances, wire diameter, weave geometry and verification methods for test sieves. Using sieves that comply with this standard ensures results are comparable between different laboratories and instruments. It is widely required in export, accreditation and quality certification processes across industry.

A standard analysis typically takes between 5 and 30 minutes, depending on the material, sample mass and number of sieves. Sieving time is usually established by a preliminary endpoint test: when the mass change on a sieve falls below a defined threshold, the analysis is considered complete. This avoids over-sieving and unnecessary cycle extension.
