Product Overview

This laboratory pulverizer represents the pinnacle of high-throughput sample preparation technology, engineered specifically to meet the rigorous demands of modern material science and industrial quality control. By utilizing a sophisticated two-stage grinding process, this equipment ensures that even the most challenging materials—ranging from soft organic tissues to hard, brittle minerals—are reduced to precise analytical fineness with unmatched speed. Its core value proposition lies in its ability to combine high centrifugal forces with a versatile rotor-and-sieve architecture, delivering consistent, repeatable results that are essential for downstream analytical procedures such as XRF, ICP, and CHN determination.

Industries ranging from agricultural research and environmental monitoring to plastic manufacturing and pharmaceutical development rely on this system for its adaptability. Whether processing grain for protein analysis, soil for heavy metal detection, or polymers for RoHS compliance, this unit provides the necessary flexibility to handle diverse sample morphologies. Its robust design is particularly suited for high-volume laboratories where operational uptime and contamination control are paramount, offering a reliable solution for both dry and wet grinding applications across a broad spectrum of material types.

Engineered for reliability under demanding conditions, the equipment features a high-torque motor and advanced cooling mechanisms that prevent sample degradation due to thermal stress. The structural integrity of the grinding chamber, coupled with precision-machined rotors, ensures long-term performance even when processing corrosive or abrasive substances. Procurement teams can invest with confidence, knowing that this unit is built to withstand the rigors of continuous industrial use while maintaining the precision required for sensitive laboratory research, ultimately streamlining the workflow from raw sample to analytical-grade powder.

Key Features

• High-Efficiency Two-Stage Grinding: This system utilizes a unique rotor-and-ring-sieve mechanism that performs primary impact pre-grinding followed by intensive shear and friction grinding, ensuring ultra-fine results in a single pass.
• Variable Speed Control: The motor provides an adjustable speed range from 6,000 to 23,000 rpm, allowing operators to fine-tune the centrifugal force and peripheral speed (up to 119 m/s) to match specific material properties.
• Advanced Thermal Management: A specially designed air passage maintains constant airflow through the grinding chamber, effectively cooling the rotor and the sample to prevent the loss of volatile components or thermal degradation.
• Intelligent SOP Management: The integrated touch control panel supports the storage of up to 20 Standard Operating Procedures (SOPs), guaranteeing consistency in multi-user environments and simplifying complex preparation workflows.
• Robust Safety Architecture: The equipment is fitted with a dual-layer protection system, comprising both electronic and mechanical locks, alongside motor overload protection to ensure operator safety and mechanical longevity.
• Versatile Accessory Ecosystem: With interchangeable rotors (6, 12, or 24 teeth) and a wide array of ring sieves, the unit can be customized for everything from coarse massive samples to the finest powders under 40μm.
• Contamination-Free Processing: All components that come into contact with the sample, including rotors and sieves, are available in stainless steel or heavy-metal-free materials to satisfy strict analytical purity requirements.
• High-Volume Capability: For industrial-scale preparation, the system can be integrated with an automatic vibratory feeder and cyclone collectors (up to 5L) to facilitate continuous processing and high-volume sample throughput.
• Precision Engineering: The 99mm diameter rotor and precision-ground ring sieves are manufactured to exacting tolerances, delivering uniform particle size distribution and reducing the need for secondary processing.
• Simplified Maintenance: The modular design allows for tool-free removal of all parts in contact with the sample, streamlining the cleaning process and preventing cross-contamination between different batches.
