Reciprocating Sieve Shaker Automatic Laboratory Particle Size Separation Equipment

Product Overview

This reciprocating automatic sieve shaker is a high-efficiency sample classification system designed to provide consistent, repeatable particle size fractioning for analytical and quality control laboratories. Built with a heavy-duty mechanical drive mechanism, the equipment delivers standardized horizontal reciprocating agitation that accelerates throughput while maintaining particle integrity. By automating the mechanical separation process, this unit provides testing laboratories with an indispensable instrument for routine batch analysis, quality inspection, and material research.

Engineered to serve across multiple demanding sectors, this shaker is widely adopted in geological exploration, industrial mineral processing, metallurgical analysis, chemical engineering, medical research, and academic testing environments. Its precise linear stroke action guarantees efficient movement of raw powders, aggregates, chemical granules, and environmental soil samples across test screen surfaces. The integrated electrical timing control ensures strict adherence to standardized testing protocols without requiring continuous operator monitoring.

Constructed for long-term operational stability and minimal maintenance, this equipment features a compact structural footprint paired with robust clamping assemblies. Whether installed on a reinforced laboratory benchtop or anchored to a solid testing facility floor, the system operates with smooth, vibration-damped mechanical precision. High build quality, reliable power transmission, and simple operational controls make this unit a dependable choice for high-volume sample preparation workflows.

Key Features

• Fixed High-Stroke Amplitude: Engineered with a dedicated 40 mm reciprocating amplitude that delivers optimal mechanical agitation force to disperse cohesive powders and separate granular materials efficiently across the entire screen area.
• Precision Reciprocating Drive: Operates at a continuous, standardized frequency of 240 cycles per minute, maintaining smooth kinematic performance to guarantee maximum reproducibility between consecutive test batches.
• Automated Electrical Timer: Equipped with an integrated 0 to 16-minute electrical timer switch that allows operators to set precise run times, automatically halting operation to eliminate human timing error during standardized sieve analysis.
• Standardized Screen Accommodations: Designed specifically to hold 300 × 220 mm rectangular test sieves, supporting both single-frame setups and multi-layer sieve stacks to perform multi-stage particle sizing in a single operation.
• Heavy-Duty Clamping System: Features robust vertical slide rods with heavy-duty wing nuts that allow rapid, secure clamping and quick release of test sieve assemblies, preventing frame loosening or sample leakage during high-frequency motion.
• Compact Vibration-Damped Footprint: Built with a space-saving structural layout and weighted base housing that minimizes vibration transmission to surrounding benchtop instruments while ensuring silent, stable operation.
• Simple Operational Interface: Designed with intuitive push-button starting controls and clear locking knobs, allowing laboratory technicians to quickly load samples, initiate automated runs, and collect accurate fractioning results with minimal setup time.
• Durable Construction & Low Maintenance: Formed from wear-resistant industrial materials and sealed internal drive elements, ensuring continuous daily operation under aggressive industrial lab environments with negligible maintenance requirements.

Operational Procedure & Maintenance Guidelines

1. Setup & Powering: Connect the system to a grounded 220V electrical supply. Set the integrated timer mechanism to the desired target sieving duration and engage the timer lock knob.
2. Sieve Loading: Place the 300 × 220 mm rectangular sieve (single unit or stacked set) onto the sieve support frame. Load the designated dry test sample into the top sieve chamber. Secure the assembly firmly by tightening the wing nuts along the slide rods.
3. Initiating Run: Press the power start button to initiate reciprocating movement. The unit operates continuously until the preset timer elapses, automatically stopping the motor. If running custom tests over 12 minutes, manually shut off the unit as required.
4. Sample Recovery: Loosen the wing nuts, remove the test sieves, and weigh the retained material on each sieve deck to calculate exact particle size distribution fractions.
5. Routine Maintenance: Ensure the unit is installed perfectly level on a sturdy workbench. Periodically check grounding reliability and keep the slide rods clean of abrasive dust particles after every testing cycle.
