Products Description
Working Principle:
The spiral airflow crushing process utilizes high-speed airflow to propel materials into the grinding chamber, where they collide with each other in a tangential direction. The materials are fractured under the combined forces of shear and impact. Compressed gas is rapidly released through a Laval nozzle, creating a heat absorption effect that dissipates the heat generated during the crushing process. This enables low-temperature crushing, preserving the material’s properties.
Performance Characteristics
- Ideal for R&D and New Product Development: The spiral air mill is particularly suited for research and development applications.
- Crystal Structure Manufacturing: It is a specialized device for processing materials with specific crystal structures.
- Particle Size Range: Capable of producing particles with a D50 range of 2–100 microns.
- Small Batch Processing: Efficiently processes small batches (starting from 5g), with maximum production capacity depending on material properties and particle size requirements.
- Production Capacity: Typically achieves 100–500g/h, with the capacity to reach up to 1000g/h for easily crushable materials.
Design Features
- Hygienic Design: The overall design is easy to clean, with no dead corners, gaps, or welding points.
- High Efficiency: Low loss rate and high yield (>95%).
- Compact and Portable: Designed for laboratory or benchtop use.
- Modular Components: The nozzle ring and mill base are separable, with the nozzle integrated into the nozzle ring.
- Independent Airflow Control: Compressed air injection for grinding is independently adjustable.
- Tool-Free Disassembly: The system can be completely disassembled without tools for easy cleaning.
- Feeding Options: Utilizes vibratory feeding, with manual feeding available as an optional customization.
Power and Compressed Air Requirements
- Power Supply: 220V, 50Hz
- Compressed Air: Requires 1m³/min at a pressure of 0.6MPa.
