Water-Cooled Pulse Dust Removal Air Classifying Ultrafine Grinder

Product Overview

This water-cooled pulse dust removal air classifying ultrafine grinder represents the next evolution in fine powder processing technology. By integrating a multi-stage grinding disc with a classifying impeller rotor and both air and water cooling, the system achieves ultrafine particle sizes down to 2000 mesh (approximately 6.5 microns) with exceptional uniformity. Its built-in pulse-jet dust collection ensures a clean, safe working environment, making it ideal for high-value, sensitive materials where purity and contamination control are paramount. Whether you are developing new pharmaceutical formulations or producing small batches of advanced ceramics, this grinder delivers consistent, reproducible results.

Designed for laboratory and pilot-scale applications, the unit processes a broad spectrum of materials—from soft herbs and grains to hard minerals and metallic compounds. Key industries include pharmaceutical R&D, nutraceutical manufacturing, cosmetic ingredient processing, and mineral research. The ability to handle both small and moderate quantities (5–30 kilograms per hour) with rapid changeover between materials makes it an indispensable tool for facilities requiring flexibility without sacrificing precision.

Engineered for durability, all product-contact surfaces are fabricated from 304 stainless steel, ensuring corrosion resistance and easy sanitation. The negative-pressure air cooling coupled with an external water chiller maintains low temperatures even during extended runs, protecting heat-sensitive materials and extending the life of critical components. With overload protection and simple, tool-free disassembly for cleaning, this system is built to perform reliably under demanding daily use while meeting GMP compliance standards.

Key Features

• Precision Air Classifying Technology: The multi-stage grinding disc and classifying impeller work in tandem to generate high centrifugal forces, ensuring narrow particle size distributions. An intuitive graduated dial with indicator allows operators to quickly adjust the cut point from 300 to 2,000 mesh without shutting down. For ultra-fine requirements, the regrind capability can push particle sizes into the nanometer range.
• Integrated Water Cooling System: Unlike conventional mills, this grinder combines negative-pressure air cooling with an external 2P water chiller. This dual cooling keeps the grinding chamber at low temperatures, preventing thermal degradation of sensitive materials such as vitamins, active pharmaceutical ingredients, and natural extracts. It also reduces wear on the high-speed spindle, ensuring consistent performance over time.
• Efficient Pulse Dust Removal: A comprehensive pulse-jet baghouse with 9 filter bags captures sub-micron dust particles before exhaust air is released. The self-cleaning pulse mechanism maintains filter efficiency, resulting in a nearly dust-free operation. This feature is critical for facilities adhering to strict environmental and worker safety regulations, as well as for preventing cross-contamination between product batches.
• High-Power Drive & Feeding System: The main motor delivers 7.5 kW at 6,000 RPM (customizable to 11 kW for higher throughput) to tackle tough materials. An automatic feeding motor smoothly delivers raw material at a controllable rate, optimizing the mill’s throughput and preventing blockages. This synergy between feed and grinding ensures steady production rates of 5–30 kg/h.
• All Stainless Steel Construction: Constructed entirely from 304 stainless steel, the mill offers exceptional corrosion resistance and is suitable for food, pharmaceutical, and chemical applications. The sanitary design with seamless welds and minimal crevices complies with GMP guidelines, facilitating thorough cleaning and validation between batches.
• Compact, All-in-One Design: The system integrates the main grinder, cyclone separator, material collection drum, pulse dust collector, and water chiller into a compact footprint. This pre-engineered arrangement saves valuable lab space and simplifies installation—just connect power and the air compressor to start operation.
• Advanced Safety & Monitoring: Built-in overload protection automatically alerts operators to abnormal loads, reducing the risk of motor burnout or mechanical failure. The enclosed process, combined with negative-pressure conveying, eliminates dust leakage and enhances operator safety, particularly when handling potent or toxic powders.
• Versatile Particle Control: The adjustable classifying wheel speed, coupled with the variable feed rate, provides direct control over the final particle size distribution. This allows researchers to achieve everything from coarse 50-mesh pre-grinding to ultra-fine 2,000-mesh polishing, all on one machine.
• Low Maintenance, High Uptime: The tool-free quick-release design for the grinding chamber and cyclone assembly enables rapid cleaning and part replacement. The air-cooled and water-cooled system minimizes thermal stress on bearings and seals, significantly extending maintenance intervals.
• GMP-Ready Validation Features: Standard features such as smooth stainless steel surfaces, easily removable components, and validated cleaning procedures support compliance with pharmaceutical and food safety regulations. Documentation packages for IQ/OQ/PQ are available upon request.
