Sieve Shaker
STANDART: EN 932-5, ISO 3310-1, ISO 3310-2, ASTM E11, 323, BS 410-1, 410-2
LT-G0022 Sieve Shaker | Time Controlled
LT-G0023 Sieve Shaker | Frequency & Time Controlled
Sieve Shaker is designed for the efficient particle-size classification of aggregate, soil and other dry granular laboratory samples. Its combined vertical and circular vibratory movement distributes the specimen across the sieve surface and helps keep sieve apertures clear during testing. The series includes a time-controlled model and a frequency & time-controlled model, both suitable for Ø200 mm and Ø300 mm test sieves.
- Combined Sieving Motion: Circular and vertical movement distributes the sample across the sieve surface.
- Digital Timer: Adjustable for test periods up to 60 minutes.
- Two Model Options: Time-controlled and frequency & time-controlled versions.
- Frequency Control: LT-G0023 allows vibration adjustment according to sample characteristics.
- Ø200 and Ø300 mm Sieve Compatibility: Supports commonly used laboratory test sieve diameters.
- Wet Sieving Support: Suitable accessories and connections allow wet sieving applications.
- Dynamic Vibration System: Provides consistent movement for rapid and repeatable classification.
- Reduced Aperture Blocking: Vertical movement helps keep particles moving across the sieve cloth.
- Heavy Sample Capability: Designed to maintain effective vibration with relatively heavy samples.
- Robust Laboratory Construction: Both models weigh approximately 86 kg.
- Power Supply: Single-phase 220–240 V, 50–60 Hz, depending on model.

Sieve Shaker for Laboratory Particle Size Analysis
The Sieve Shaker provides controlled and repeatable mechanical sieving for aggregate, soil and other granular laboratory samples. The system applies a combination of vertical and circular movement to a stack of test sieves, allowing particles to move continuously across the screening surface.
This controlled action reduces the differences that can occur during manual sieving. It also helps laboratories perform routine particle-size classification under more consistent conditions.
Vertical and Circular Sieving Motion
The machine combines vertical oscillation with circular movement. Circular motion distributes the sample over a wider section of the sieve surface, while vertical movement encourages smaller particles to pass through the appropriate apertures.
Liya states that the vertical movement is fixed to keep the specimen moving on the sieve surface and to help prevent aperture binding. This arrangement supports faster and more reproducible sieving.
Digital Time Control
Both models incorporate a digital timer adjustable up to 60 minutes. The operator selects the required sieving duration before starting the test.
Once the selected period is complete, the sieving cycle can be stopped consistently. This avoids manually timing each analysis and helps standardize repeated laboratory procedures.
Time and Frequency Controlled Models
The LT-G0022 is intended for routine applications where controlled test duration is the main requirement.
The LT-G0023 adds frequency adjustment. This allows the operator to adapt vibration intensity according to material mass, particle shape and sieving behaviour. The additional control is useful when laboratories work with a wider variety of sample types.
Ø200 and Ø300 mm Test Sieves
The Sieve Shaker accepts Ø200 mm and Ø300 mm laboratory sieves. Multiple sieves can be arranged from the largest aperture at the top to the smallest aperture at the bottom.
During operation, coarse particles remain on the upper sieves while finer particles move down through the stack. The retained material can then be weighed to calculate particle-size distribution. Liya’s Turkish product description also states that the unit can support wet sieving with the appropriate setup.
Test Sieve Standards
Liya lists EN 932-5, ISO 3310-1, ISO 3310-2, ASTM E11, ASTM E323, BS 410-1 and BS 410-2 on the product page.
ISO 3310-1:2016 remains current and covers metal wire-cloth test sieves, while ISO 3310-2:2013 remains current for perforated metal-plate test sieves. ASTM E11-24 is the current ASTM specification for woven-wire test sieve cloth and test sieves, while ASTM E323-11(2021) covers perforated-plate sieves.
As a result, the Sieve Shaker combines controlled vibration, digital timing and multiple sieve-size compatibility for routine particle-size analysis in aggregate, soil and general materials laboratories.
