Small Laboratory Vibrating Sieve Shaker for Precise Particle Size Analysis

Product Overview

This vibrating sieve shaker provides a fast, accurate, and repeatable method for particle size analysis in laboratory settings. By delivering a powerful three-dimensional vibration motion—generated by dual eccentric weights on the motor shaft—it ensures every particle contacts the sieve mesh, reducing analysis time and improving separation efficiency compared to manual sieving. Its performance meets the requirements of major international standards for sieve analysis, ensuring compliance in ISO, ASTM, and GMP environments.

The equipment is designed for versatility, handling dry powders, wet slurries, and granular samples with equal ease. Operators can fine-tune the vibration pattern by adjusting the phase angle between the upper and lower weights, optimizing material flow for different sample types—from fine cohesive powders to large abrasive particles. This capability makes it a cornerstone for quality assurance across food, pharmaceutical, chemical, ceramic, metallurgical, and mining industries, where accurate gradation data directly impacts product quality.

Built with durability in mind, this unit features a rugged frame and precision components that withstand continuous daily use. The integrated digital timer and simple, tool-free sieve stacking system streamline workflow, while the enclosed design contains dust and liquids, promoting a clean laboratory environment. The straightforward interface requires minimal training, allowing new users to achieve accurate results quickly. Count on this system for reliable, low-maintenance performance in even the busiest testing labs.

Key Features

Engineered for optimal performance and user convenience, this vibrating sieve shaker incorporates the following advanced features:

• Three-Dimensional Vibration Technology: Unlike traditional shakers, this model produces simultaneous horizontal, vertical, and inclined vibration, promoting thorough sample dispersion and preventing sieve blinding. The result is faster, more accurate separations, especially for difficult-to-sieve materials.
• Quick, Tool-Free Sieve Changes: The rapid-clamping mechanism allows adding or removing sieves in seconds—no tools required. Stack up to 7 standard 50‑mm‑high sieves (or up to 8 depending on frame height) for multi-fraction analysis in a single run.
• Adjustable Vibration via Eccentric Weights: By altering the angular relationship of the two weights, users can control the direction and intensity of vibration. This customization suits a wide array of sample types, from fragile, low-density powders to heavy, abrasive granules.
• Precise Digital Timer: An integrated timer enables settings from 1 to 30 minutes, with automatic stop for unattended operation. This ensures consistent sieving durations across tests, enhancing reproducibility and freeing operators for other tasks.
• Broad Mesh Compatibility: This system accepts test sieves ranging from coarse 3.5 mesh (5.6 mm apertures) to ultra‑fine 400 mesh (38 µm), covering the full spectrum of common laboratory sieving applications without the need for additional equipment.
• Clean, Contained Operation: The fully enclosed design with effective seals prevents powder dust escape, liquid splashing, and particle jumping, keeping your lab clean and minimizing cross‑contamination risks.
• Compact, Benchtop-Friendly Build: With dimensions of only 340×340×670 mm and a weight of 30 kg, this shaker occupies minimal bench space while delivering industrial-grade vibration force, making it perfect for laboratories of any size.
• Energy-Efficient & Durable Motor: The 0.1 kW motor operates on standard single‑phase 220 V, 50 Hz power, consuming very little energy while maintaining a consistent 3000 rpm vibration speed for thousands of test cycles.

These capabilities combine to make this shaker an indispensable tool for any particle characterization laboratory.
