Product Overview
This airflow ultrafine pulverizer is a high-performance laboratory-scale micronization system that integrates mechanical impact grinding with advanced air cyclone separation. It reliably converts a wide range of dry materials into ultra-fine powders, achieving particle sizes down to the micron range. The equipment is meticulously designed to combine the strengths of mechanical and pneumatic milling, ensuring efficient size reduction with minimal heat generation and consistent particle distribution.
Primarily targeted at R&D institutions, quality control laboratories, and small-scale production environments, this system excels in processing pharmaceuticals (including traditional Chinese medicines), chemicals, food ingredients, cosmetics, ceramics, and various advanced materials. Its ability to handle both brittle and fibrous substances with equal efficacy makes it a versatile tool for material science and formulation development.
Engineered for demanding continuous operation, the unit incorporates a high-speed precision motor, premium imported bearings, and rigorously selected electrical components. Its fully enclosed design ensures operator safety and clean processing, while the simple construction enables rapid cleaning between batches. This robust engineering delivers reliable, maintenance-friendly performance even under intensive laboratory use.
Key Features
- Ultra-Fine Grinding Performance: Delivers final particle sizes as fine as 1000 mesh (approximately 15 µm) for hard and brittle materials, and 600 mesh (approximately 25 µm) for fibrous substances. Typical D98 values reach 12–44 µm for brittle and 40–100 µm for fibrous materials, ensuring narrow size distributions suitable for demanding analytical and processing requirements.
- High-Speed Rotor Assembly: A 23,000 rpm direct-drive motor generates powerful impact forces, rapidly pulverizing material with minimal heat buildup. The precision-balanced rotor and specially shaped blades maximize grinding efficiency while reducing energy consumption.
- Intelligent Airflow Separation: The integrated cyclone system harnesses the airstream created by the rotor to instantly separate and collect fine particles. This eliminates the need for sieves, minimizes powder loss, and ensures a clean working environment by exhausting only purified air through the filter bag.
- Compact, Space-Saving Design: With dimensions of 260×240×460 mm and a weight of only 10 kg, this unit easily fits on a standard laboratory bench. Its portability allows flexible placement and redeployment across different workstations without sacrificing performance.
- Continuous Feed, Single-Operator Operation: The straightforward, continuous feed mechanism allows one person to operate the machine efficiently. Simply connect to a 220 V power supply, load the material, and collect the ground powder—no complex setup or supervision required.
- Superior Safety and Cleanability: The fully enclosed grinding chamber prevents direct operator contact with moving parts. Cleaning is quick and tool-free, as the chamber and components are easily accessible and washable, making it ideal for multi-material workflows.
- Long-Lasting Durability: Built with high-grade electrical elements and Japanese-manufactured bearings, the system is designed for thousands of hours of trouble-free service. Its robust construction withstands the rigors of daily lab use, providing a long service life with minimal maintenance.
