Automatic Standard Sieve Shaker for Laboratory Particle Size Analysis and Granulometric Sample Preparation

Product Overview

This automatic standard sieve shaker represents an advanced solution for precision particle size analysis, material grading, and sample preparation in scientific research and industrial quality control laboratories. Utilizing a high-efficiency dual-action composite sieving motion that combines continuous horizontal planar swinging with synchronous vertical tapping, the equipment facilitates fast, thorough, and highly reproducible particle separation across a broad granularity spectrum from 6.0 mm down to 0.045 mm (45 µm).

Engineered specifically for demanding material science applications, this system plays a critical role in evaluating sand grain distribution in geological clastic rock studies, inspecting aggregate fractions for civil construction materials, monitoring pharmaceutical powder and granule morphology, and ensuring consistent particle sizing in powder metallurgy and chemical manufacturing. Its versatile design accommodates up to eight standard testing sieves, allowing operators to achieve complete granulometric distribution profiles in a single rapid test cycle.

Built with an emphasis on operational reliability, cleanroom compatibility, and operator safety, this system features a maintenance-free oil-free speed reduction mechanism, an automated lid-locking quick-clamp system, and an enclosed dust containment structure. Whether deployed in routine production testing or rigorous R&D environments, the equipment delivers unwavering performance, strict adherence to international sieving standards, and maximum operational efficiency.

Key Features

• Dual-Action Composite Sieving Kinematics: Combines smooth horizontal planar gyratory motion (221 cycles/min at a 12.5 mm radius of gyration) with aggressive vertical impact tapping (149 taps/min with a 10 mm stroke length). This combined kinetic action rapidly breaks particle agglomerates, prevents screen blinding, and ensures fine particles pass through mesh apertures efficiently.
• Rapid Sieve Clamping with Auto-Locking Lid: Incorporates an ergonomic quick-release clamping frame designed to hold up to 8 standard Ø200 × 50 mm test sieves. The automated lid lock applies consistent downforce pressure, securing the sieve stack during high-intensity vertical tapping without requiring manual bolt tightening.
• Oil-Free Lubricated Transmission: Utilizes a fully enclosed, oil-free internal speed reduction mechanism. This clean technology eliminates the risk of gear oil leaks, removes lubricant replenishment requirements, reduces operational noise, and maintains pristine laboratory conditions.
• Programmable Digital Controller with Memory: Features an intuitive digital control panel with a clear text display. The built-in memory stores up to three customized operation modes, enabling rapid execution of standard operating procedures and eliminating operator variation between testing batches.
• Enclosed Dust Containment Architecture: Engineered with a dust-tight outer cabinet structure that captures fine particulates generated during sieving. This design dramatically minimizes ambient dust leakage, ensuring full compliance with environmental health and safety standards.
• Dedicated Dust Collector Port: Features a pre-installed extraction interface ready for connection to external laboratory vacuum or central dust collection systems, facilitating real-time dust extraction when processing toxic, corrosive, or extremely fine powders.
• High Capacity Multi-Tier Stacking: Capable of handling a feed loading mass of up to 200 grams per sieve layer across an 8-layer sieve stack, supporting processing throughputs up to 0.2 metric tons per hour (0–0.2 t/h) for high-volume sample preparation.
• Heavy-Duty Vibration-Damped Chassis: Constructed with a solid 110 kg base frame and compact 600 × 380 × 822 mm footprint. The weighted chassis absorbs internal mechanical inertia, maintaining absolute stability on laboratory benchtops without structural drifting.
