High Frequency Cabinet Type Three-Dimensional Rotary Vibrating Sieve Shaker for Dry Sieving and Particle Classification

Product Overview

This cabinet type three-dimensional rotary vibrating sieve shaker represents the next generation in dry particle size analysis for laboratory and light industrial environments. The system employs a proprietary three-dimensional vibration mechanism—combining 1500 rpm horizontal rotation with a vertical oscillation of 10 mm amplitude—to fluidize the sample bed and accelerate passage through stacked sieves. This motion pattern ensures thorough, even distribution of material across each sieve, minimizing blinding and delivering sharp, reproducible cut points.

Engineered for powders, granules, small lumps, fibers, and any free-flowing or loosely agglomerated materials, the unit is ideal for quality control, incoming inspection, and R&D formulation tasks. Target industries include pharmaceuticals, chemicals, food processing, mining, ceramics, and advanced material manufacturing. Its ability to handle loads up to 5 kg and process particle sizes from 20 microns to 125 millimeters makes it versatile for both fine powders and coarse aggregates.

Constructed within a floor-standing, dust-proof and sound-insulated cabinet, this device meets the rigorous demands of continuous laboratory use. Every component—from the electromagnetic drive to the quick-release sieve clamp—is selected for longevity and tested to CE and ISO9001 standards, ensuring consistent performance with minimal maintenance. The integrated digital controller with password protection further guarantees process security and operator-safe reproducibility.

Key Features

• High-Frequency Three-Dimensional Vibration: At 1500 oscillations per minute, the drive system superimposes a rapid horizontal circular motion with a precisely timed vertical lift, creating a true 3D trajectory. This action causes particles to rotate, bounce, and migrate evenly across the entire sieve surface, drastically reducing analysis time and preventing the material buildup that can distort results.
• Multi-Layer Sieve Stacking: The unit accommodates 1 to 5 standard 200 mm diameter analytical sieves plus a lid and pan, all secured between the clamping plate and the base. This enables simultaneous fractionation into up to six size classes in a single automated cycle, improving throughput and eliminating the between-sample handling errors common with single-sieve methods.
• Precision Amplitude Control: A fixed 10 mm vertical stroke ensures consistent throwing height across all load conditions, which is critical for reproducible sieving especially with fine, cohesive, or low-density powders. The mechanical design avoids amplitude drift, guaranteeing that every run meets the same separation standards as the last.
• Ergonomic Cabinet Design: The floor-standing enclosure features a pneumatic-assisted flip-top lid, reducing physical effort during sieve changes. A large, thick safety-glass viewing window coupled with bright LED interior lighting allows real-time observation of the sieving progress without compromising sound or dust containment. The cabinet's layout also facilitates maintenance access and easy cleaning.
• Advanced Digital Controller: The intuitive interface offers timed operation (up to 999 minutes), intermittent sieving to break up agglomerates, and a one-key reset for rapid method recall. Password lock prevents unauthorized tampering with parameters, while an audible alarm signals cycle completion or faults, allowing unattended operation.
• Comprehensive Dust and Sound Isolation: The sealed, IP65-rated enclosure effectively contains fine particulate inside the sieving chamber, protecting the laboratory environment and operator health. High-density acoustic insulation reduces operational noise to approximately 70 dB, well below typical workplace limits, enabling comfortable operation even in shared labs.
• Quick-Release Sieve Clamping: A tool-free, lever-actuated clamping mechanism compresses the sieve stack securely and releases it with a single motion. Sieves can be loaded or replaced in under 30 seconds, minimizing turnaround between tests and maximizing daily sample throughput.
• Robust Power Versatility: The 550 W motor can be configured for 100–120V or 200–240V single-phase, 50/60 Hz, and the unit comes pre-wired with your choice of national, European, American, or British standard plug. This global compatibility simplifies procurement for multinational organizations and ensures easy integration into any lab electrical infrastructure.
