Water Cooled Airflow Ultra Fine Grinder for Low Temperature Material Processing

Product Overview

This water-cooled airflow ultra-fine grinder is an advanced sample preparation tool engineered for low-temperature comminution of dry, heat-sensitive materials. By integrating a high-speed impact rotor with cyclonic air classification and a water-cooled jacket, it delivers precise, uniform particle size reduction without thermal damage. The system is purpose-built for laboratories and small-scale production environments where preserving the chemical integrity of processed powders is paramount.

Commonly deployed in pharmaceutical R&D, herbal medicine processing, food ingredient development, and advanced ceramics research, the unit accommodates a wide input material spectrum. Its ability to maintain sub-ambient temperatures—via the combination of forced air and chilled water circulation—makes it the preferred choice for thermolabile substances such as certain active pharmaceutical ingredients, botanical extracts, and specialty polymers.

Built with premium components including a pure copper-wire motor and Japanese high-speed bearings, the equipment offers long service life under demanding continuous-use regimes. The fully enclosed, screen-free design simplifies cleaning, minimizes cross-contamination risks, and supports GLP compliance. With a benchtop footprint and straightforward one-person operation, it integrates seamlessly into shared lab workspaces.

Key Features

• Dual Cooling for Low-Temperature Milling: The integrated water jacket envelops the grinding chamber, circulating chilled water via a 45 W pump (max flow 2500 L/h) to rapidly dissipate heat. Combined with the natural air flow generated by the high-speed rotor, this dual mechanism keeps processing temperatures well below material degradation thresholds. An optional recirculating chiller can further lower jacket coolant to -35°C for ultra-low-temperature requirements.
• Precise Fineness Control via Vortex Adjustment: Unlike fixed-screen mills, this system employs a variable vortex ring to regulate particle residence time and classification efficiency. Operators can continuously tune fineness from 80 to 1000 mesh without tool changes, enabling rapid adaptation to different materials and specifications. This design ensures narrow particle size distributions for superior product quality.
• High-Speed Motor & Bearings for Sustained Performance: A 1.8 kW pure copper-wire motor drives the rotor at 25,000 rpm, delivering powerful impact forces that shatter particles instantly. Japanese-imported, high-precision bearings ensure stable, low-vibration operation even under continuous loads. The motor’s robust construction and efficient heat dissipation allow for extended run times without performance drift.
• Hygienic, Screen-Free Collection System: The cyclone separator and fabric bag collector eliminate the need for mesh sieves, which can clog, wear, and introduce contaminants. Product recovery is virtually complete, and the collection assembly can be easily removed, cleaned, and sanitized. This closed system protects operators from dust exposure and meets stringent hygiene requirements.
• Compact, Benchtop-Ready Design: Weighing only 13 kg and occupying minimal bench space, this unit can be placed directly on a laboratory table, no special mounting required. Its lightweight construction does not compromise durability; the frame and housing are engineered for rigidity and vibration damping.
• Continuous Feed & Simple Operation: A top-mounted hopper accepts continuous material input while the mill runs, eliminating batch cycling. A single power switch starts the motor and cooling pump simultaneously. The intuitive design allows one operator to manage the entire process, reducing labor costs.
• Safe, Easy Cleaning & Dust-Free: The completely enclosed design eliminates operator exposure to high-speed parts and fine powders. A transparent cyclone and removable collection jar allow visual inspection and swift cleaning; all parts in product contact are water-washable and autoclavable. This design meets GMP and laboratory safety standards.
• Low-Noise Operation: Advanced acoustic dampening and precision balancing keep operational noise within comfortable levels, enhancing the laboratory work environment.
• Versatile Optional Upgrades: Enhance the system with a water chiller (5°C or -35°C) for precise temperature control, or add a vibratory feeder for uniform, automated material dosing. These modules integrate seamlessly, expanding the grinder’s utility in critical applications.

Why Choose This Product

• Uncompromised Low-Temperature Performance: The water jacket and air cooling system work synergistically to keep grinding zones cool, preventing thermal decomposition even with prolonged operation. This is critical for preserving the potency of expensive bioactive compounds and high-value thermoplastics, ensuring you get the maximum return from raw materials.
• Engineered for Reproducibility: From the dynamically balanced rotor to the precision-adjustable vortex ring, every subsystem is designed to deliver consistent particle size distributions from batch to batch. Tight manufacturing tolerances and rigorous QC testing mean your process parameters remain stable over years of service.
• Low Maintenance, High Productivity: The screen-free cyclone collector and durable bearings drastically reduce routine maintenance. Operators simply empty the collection bag and wipe down surfaces; no mesh cleaning, replacement, or screen calibration. This translates to more uptime and fewer service interruptions.
• Flexible Integration and Future-Proofing: The unit’s modular design allows easy addition of a chiller for ultra-low-temperature work or a vibratory feeder for automated feeding. As your applications expand, the machine grows with you, avoiding the need for a capital-intensive replacement.
