Product Overview
The Dry Sieving Shaker Machine is a professional laboratory instrument for precise particle size analysis and classification of dry powder and granular materials. It uses an advanced electromagnetic drive system to generate three-dimensional throwing motion, ensuring even sample distribution across the entire sieve surface for rapid and accurate screening results.
This laboratory sieve shaker is widely used in quality control, R&D, and production testing across pharmaceuticals, metallurgy, food processing, chemicals, mining, and construction materials.
Our Dry Sieving Shaker Machine delivers consistent, repeatable, and reliable results – helping you optimize product quality and reduce production risks.From pharmaceutical powder grading to mining ore analysis, our customers have achieved up to 95% improvement in sieving reproducibility with our electromagnetic drive technology.
Key Features
1. High-Precision Sieving (±1μm Accuracy)
Electromagnetic drive delivers accurate, repeatable results with accuracy up to ±1μm. No mechanical wear, consistent performance over thousands of cycles.
2. 3D Throwing Motion for Optimal Distribution
Three-dimensional sieving action eliminates particle segregation and ensures every particle has an equal chance of passing through sieve apertures.
3. Digital Parameter Control
All parameters – time (01-99 min), amplitude (0.2-3.0 mm), and interval (00-99 s) – are digitally preset, eliminating operator variability.
4. Dry & Wet Sieving Compatibility
Supports both dry and wet sieving in the same equipment – ideal for laboratories handling diverse sample types.
5. Maintenance-Free Operation
Unlike mechanical shakers, our electromagnetic drive requires no lubrication or belt replacements – reducing downtime and operating costs.
6. Multi-Layer Sieve Structure (Up to 9 Fractions)
Accommodates up to 9 sieve layers simultaneously. Compatible with 100mm, 150mm, 200mm, and 203mm (8-inch) sieves.
7. Intelligent LED Touch Screen
User-friendly touch screen with intelligent control – set parameters, monitor status, and store customized programs.
8. Intermittent Vibration – Anti-Clogging
Adjustable 00-99 seconds pause prevents sieve mesh clogging, improving efficiency for fine or sticky materials.

Working Principle
Electromagnetic Drive System
The machine uses an electromagnetic drive that converts electrical energy directly into mechanical vibration – delivering instant start/stop response and precise amplitude control without mechanical hysteresis.
Three-Dimensional Throwing Motion
Electromagnetic force creates a three-dimensional throwing motion that propels particles upward and forward in a circular-elliptical pattern. This ensures even distribution, maximizes sieving area, and achieves higher separation efficiency than conventional vibratory motion.
Optimized Parameter Control
Adjustable amplitude and frequency settings allow optimization for different materials:
Fine powders (< 100 μm): Low amplitude (0.2-0.5 mm) prevents particle loss.
Coarse granules (> 1 mm): High amplitude (1.0-3.0 mm) ensures efficient separation.
The intermittent vibration function pauses sieving at preset intervals, preventing sieve blinding and ensuring accurate results for sticky or electrostatically-charged materials.

Case Study – Pharmaceutical Powder Sieving
Challenge: A pharmaceutical manufacturer had inconsistent tablet quality due to variable powder particle size. Their mechanical sieve shaker produced poor reproducibility and frequent clogging.
Solution: We supplied our Dry Sieving Shaker with electromagnetic drive and intermittent vibration. Digital controls standardized sieving across batches.
Result: Within 3 weeks of implementation, sieving analysis reproducibility improved by 95%, mesh clogging was virtually eliminated, and batch rejection rates dropped by 12% – saving the client approximately $47,000 annually in reduced waste and rework.

Frequently Asked Questions
1. What is the difference between dry and wet sieving?
Dry sieving is for free-flowing powders. Wet sieving is for suspensions, very fine particles (< 45 μm), or materials prone to agglomeration. Our machine supports both.
2. How to choose the right amplitude?
Fine powders (< 100 μm): 0.2-0.5 mm
Medium particles (100 μm – 1 mm): 0.5-1.5 mm
Coarse materials (> 1 mm): 1.5-3.0 mm
3. What maintenance is required?
Maintenance-free – no lubrication or belt replacement. Simply clean sieves after use and periodically check the clamping system.
4. What materials can be tested?
Cement, chemicals, coffee, construction aggregates, fertilizers, flours, grains, metal powders, minerals, plastics, sand, seeds, soils, spices, and more.
5. What is intermittent vibration mode?
Auto-pauses sieving at preset intervals (00-99s) to prevent mesh clogging – critical for fine, sticky, or electrostatically-charged materials.
6. How many sieve layers can be used?
Up to 9 sieve layers plus lid and bottom pan – full particle size distribution in a single run.
7. What is the warranty and return policy?
24-month warranty against manufacturing defects. 30-day satisfaction guarantee – full refund if not satisfied (terms apply). All machines are securely packed in export-grade wooden cases for safe shipping.
8. Do you provide customized solutions?
Yes – voltage options, custom sieve diameters, specialized clamping, tailored parameter presets. Response within 48 hours.
