Laboratory Air Jet Sieving Machine for Fine Powder Particle Size Analysis and Deagglomeration

Product Overview

This high-precision air jet sieving system represents the pinnacle of particle size analysis technology for fine, dry powders that are otherwise difficult to process using traditional vibratory methods. By utilizing a sophisticated aerodynamic principle, the equipment effectively separates and deagglomerates particles, ensuring that even the most challenging materials—such as those prone to electrostatic charging or agglomeration—are analyzed with absolute accuracy. The core value proposition lies in its ability to deliver repeatable, NIST-traceable results while significantly reducing the processing time required for sub-sieve size ranges.

Primarily engineered for research and development laboratories and quality control environments, this unit is indispensable across the pharmaceutical, chemical, mineral, and food processing industries. It serves as a critical tool for ensuring material consistency in products like active pharmaceutical ingredients (APIs), toner powders, pigments, and advanced ceramics. Whether used for routine quality checks or complex material characterization, the system provides a robust solution that bridges the gap between manual laboratory testing and industrial-scale production requirements.

Designed for reliability and long-term performance under demanding conditions, the equipment features a durable housing and high-quality internal components that resist wear from abrasive materials. The integration of digital controls and a motorized rotating nozzle ensures that the sieving action remains consistent regardless of the operator, providing industrial buyers with the confidence that their data integrity remains uncompromised. This system is built to withstand the rigors of continuous laboratory use, maintaining its precision through thousands of cycles without the drift commonly associated with mechanical sieving methods.

Key Features

• Advanced Air Jetting Technology: The equipment utilizes a high-velocity air jet delivered through a rotating nozzle to effectively deagglomerate fine particles and prevent mesh blinding. This aerodynamic action ensures that even cohesive materials are separated efficiently, providing a level of accuracy that mechanical vibration cannot match for particles as small as 5 microns.
• Precision-Engineered Rotating Nozzle: A specially designed internal nozzle features digitally controlled rotation speeds ranging from 5 to 55 min⁻¹. This ensures uniform air distribution across the entire surface of the sieve mesh, resulting in highly reproducible sieving results and eliminating "dead zones" where particles might settle.
• Intelligent Vacuum Management: The system operates by creating a controlled negative pressure environment. Users can adjust the chamber vacuum between 20 and 99 mbar, allowing for the fine-tuning of air flow intensity based on the specific density and fragility of the sample material being processed.
• Comprehensive SOP Management: To support laboratory standardization, the unit can store up to 9 Standard Operating Procedures (SOPs) plus a Quick Start mode. This feature allows for the rapid recall of validated parameters including time, vacuum level, and nozzle speed, ensuring consistent testing protocols across different shifts and locations.
• Universal Sieve Compatibility: The system is designed to accommodate standard analysis sieves with a diameter of 203mm (8 inches) or 200mm (via a dedicated adapter). This flexibility allows procurement teams to utilize existing sieve inventories while maintaining the high performance of air jet separation.
• Digital Control and Connectivity: Equipped with a clear digital display and an RS232 interface, the unit allows for precise parameter adjustment and seamless data export. This is essential for modern labs requiring electronic record-keeping and integration into Laboratory Information Management Systems (LIMS).
• Robust Dry Sieving Performance: Optimized specifically for dry material applications, the system excels at processing pigments, detergents, and powdered minerals that tend to clog standard sieves. The continuous purifying effect of the air flow keeps the mesh open throughout the entire test cycle.
• Manual and Automatic Control Options: The unit offers the flexibility of manual pressure control for exploratory research or automatic pressure control for standardized testing, providing the versatility needed for both R&D and high-throughput quality control.
