Product Overview
This water-cooled pulse jet ultrafine grinder integrates high-speed impact milling with cyclonic separation, enabling continuous feed and discharge of dry materials down to 200 mesh (74 µm) without filter screens or clogging. An integrated water jacket circulates chilled water around the grinding chamber, while a programmable pulse jet system clears the collection zone at adjustable intervals. This dual cooling approach maintains low processing temperatures, making the unit particularly effective for heat-sensitive, oily, or fibrous substances. All material contact components are crafted from SUS304 stainless steel, meeting rigorous hygiene standards for food, pharmaceutical, and cosmetic applications.
Engineered for laboratories, pilot plants, and small-scale production, the system features a variable-speed 2.6 HP motor (4,000–24,000 RPM) to accommodate diverse materials—from hard grains and botanicals to soft polymers and organic waste. Safety interlocks, a motor overload protector, and an anti-spill feed design ensure safe, uninterrupted operation. Compact dimensions (420×330×460 mm) and a weight of 18.3 kg allow easy integration into crowded lab spaces, while quick-release fasteners simplify cleaning between batches.
Key Features
- Water Cooling Jacket & Programmable Pulse Jet: The integrated water jacket circulates chilled water (or ice water) around the grinding chamber, drawing away heat generated by high-speed impact. An automatic pulse jet system connects to an external air compressor and delivers timed air bursts into the collection vessel. Both interval and duration can be set via a simple controller, preventing buildup of powdery or oily residues. This temperature regulation is critical for preserving essential oils, vitamins, and other thermolabile components.
- High-Speed Micronization & Cyclonic Separation: Equipped with a 2.6 HP motor and precision-ground SUS420 blades (heat-treated to HRC 50), the rotor reaches peripheral speeds sufficient to pulverize hard, fibrous materials into particles below 200 mesh. The milled powder is carried by the airstream into a cyclone separator, where centrifugal force separates the product from the air—no screen or filter is needed, eliminating clogging and enabling continuous operation.
- Full Stainless Steel Construction: All components in contact with the product are fabricated from SUS304 stainless steel, including the grinding chamber, blade carrier, and collection bin. This ensures corrosion resistance, easy sanitation, and compliance with GMP, HACCP, and FDA requirements for food, cosmetic, and pharmaceutical manufacturing.
- Adjustable Speed & Capacity: The variable-frequency drive allows smooth speed regulation between 4,000 and 24,000 RPM. Throughput ranges from 1 to 5 kg/hr depending on material characteristics—lighter, finer powders can be produced at higher speeds, while coarse, dense materials benefit from lower RPM. This flexibility accommodates a broad spectrum of R&D and pilot-scale tasks.
- Enhanced Safety & Operator Protection: A magnetic safety switch on the grinding chamber cover prevents the motor from starting unless the lid is securely closed. The feed chute is designed with an anti-spill lip to reduce dusting. Motor overload protection shuts down the unit if excessive amperage is detected, preventing coil burnout.
- User-Friendly Maintenance & Durability: Tool-less quick-release clamps allow the collection bin to be removed in seconds for cleaning or sample retrieval. The motor bracket is hinged for tilting, exposing the internal chamber without removing the machine from the bench. Hardened blades maintain sharpness over hundreds of hours of operation, and all wear parts are easily accessible for replacement.
- Compact, Portable Footprint: Measuring just 420 mm × 330 mm × 460 mm and weighing 18.3 kg, the grinder fits on a standard laboratory bench or cart. Its small size makes it easy to move between workstations or store when not in use.
- Low Noise & Vibration: The dynamic balance of the rotor assembly and the use of high-quality bearings minimize vibration, while the motor’s design reduces noise output to comfortable levels, suitable for continuous use in open lab environments.
Applications
The versatility of this grinder makes it suitable for a wide array of materials and industries. Below are representative use cases:
| Application | Description | Key Benefit |
|---|---|---|
| Food & Nutraceutical Ingredient Processing | Micronizing dried foods like soybeans, black beans, turmeric, and ginger into ultrafine powders increases surface area for enhanced solubility and nutrient bioavailability. The water-cooled grinding prevents thermal degradation of vitamins and flavors. | Preserves nutritional quality and natural taste while achieving uniform particle size. |
| Pharmaceutical & Herbal Medicine | Pulverizing traditional Chinese medicines such as Reishi mushroom, ginseng, deer antler, and pearl into fine powders improves extraction efficiency and absorption. Consistent fineness ensures accurate dosing in capsules, tablets, or topical preparations. | Ultra-fine particles boost active compound release and therapeutic efficacy. |
| Cosmetic & Personal Care | Reducing botanicals like lavender, rosemary, and rose petals to micronized powders creates smooth, premium-quality ingredients for creams, masks, and scrubs. The low-temperature process protects delicate essential oils and colors. | Ensures silky texture and preserves botanical activity in finished formulations. |
| Chemical & Material Science | Grinding industrial materials like alumina, vermiculite, and microcrystalline ceramics to sub‑100 µm sizes for advanced composites, catalysts, and coatings. The hardened blades handle abrasive media while the pulse jet system prevents caking of hygroscopic powders. | Delivers consistent particle size distribution for reproducible material properties. |
| Agricultural & Feed Research | Processing plant materials (soybean hulls, crab shells, garlic peels) for digestibility studies or functional feed additives. The continuous operation and anti-clog features are ideal for fibrous, high‑moisture residues. | Enables efficient, low-cost sample preparation for large trial batches. |
| Spice & Seasoning Production | Creating ultra-fine spice blends (e.g., chili, cinnamon, cumin) with improved dispersion and flavor release. Quick chamber release allows fast changeovers between formulations, reducing cross-contamination risk. | Maximizes flavor intensity and batch uniformity while minimizing production downtime. |
| Tea & Instant Beverage Powdering | Micronizing green tea, oolong, or coffee beans into instant powder without the bitterness caused by overheating. Water jacket cooling holds temperature below volatile aromatic thresholds, preserving original profile. | Maintains fresh aroma and taste, delivering premium instant beverage products. |
| Waste Valorization & Biopolymer Extraction | Downsizing organic waste streams—crab and shrimp shells for chitosan extraction, or vegetable trimmings for composting. The durable construction and overload protection tackle mixed, irregular feedstocks reliably. | Supports sustainable practices by converting waste into valuable raw materials. |
