What Is a Multi-deck Laboratory Vibratory Sieve Shaker？
A multi-deck laboratory vibratory sieve shaker is a precision instrument for particle size analysis and material grading in laboratory settings. Unlike single-deck units, it uses a stacked configuration of test sieves with progressively smaller mesh openings. Material placed on the top sieve is subjected to vibration, causing particles to pass through successive layers until each sieve retains a specific size fraction. This delivers complete particle size distribution data in a single operation, eliminating sequential runs and significantly reducing testing time.
Key specs at a glance: Stackable 1–8 test sieves · 20 μm–3 mm particle size range · Operating noise < 50 dB · Sieve changeover ≤ 1 minute

Key Features
Quick-change sieve clamping – Sieve changeover in ≤ 1 minute, minimizing downtime between tests.
Optional ultrasonic deblinding – Effective for particles down to 20 μm, prevents mesh clogging for ultra-fine powders.
Multi-layer sieving capacity – Up to 8 sieves including bottom pan, separates 2–7 particle fractions in one run.
Automatic timer with shut-off – Programmable duration with auto-stop, ensuring repeatable results.
Compact low-noise operation – Benchtop design, operating at < 50 dB, suitable for shared labs.
Dry and wet sieving support – Compatible with both processes using stainless steel or nylon mesh.
Lightweight and portable – No fixed installation required, easily movable between workstations.
Durable construction – Built for continuous lab use with minimal maintenance.
Easy to operate – Intuitive control panel with clear display, minimal training required.
Versatile application – Suitable for powders, granules, liquids, and slurries across multiple industries.
Recent project
A multi-deck laboratory vibratory sieve shaker was recently supplied to a pharmaceutical R&D center for API powder grading. The S-200 model with ultrasonic deblinding enabled simultaneous 5-fraction particle size analysis down to 20 μm in a single run, reducing testing time by over 60% compared to their previous sequential method.
