### Core Function & Application This WFJ Super Micro Fine Grinder is designed specifically for materials like lotus root, spices, and herbs that require precise, dust-free fine grinding. Unlike standard mills, it features a built-in pneumatic classification system, eliminating the need for sieves while ensuring consistent particle size. It is widely used in food, pharmaceutical and chemical industries, where uniform powder quality is critical. The three-part design (main unit, auxiliary unit, control panel) ensures stable, continuous operation even with moisture-sensitive or fibrous materials.
### Tailored Advantages for Lotus Root & Spices - **Pneumatic Classification System**: Adjust particle size from 80 to 600 mesh by changing the classifier speed, no sieve replacement required. - **Simple, Compact Design**: Easy installation and low-maintenance structure, with minimal downtime for cleaning or part checks. - **Premium Components**: Equipped with well-known brand motors, bearings and electrical parts, ensuring reliable, long-term performance. - **Fully Dust-Free Operation**: Integrated dust collection system captures all fine particles, preventing cross-contamination and material loss. - **Versatile Material Compatibility**: Handles both fibrous lotus root and hard spices with equal efficiency, making it ideal for multi-product processing lines.
### Design & Working Principle The WFJ Super Micro Fine Grinder consists of three core units, each optimized for fine powder production: 1. **Main Grinding Unit**: Raw material (like lotus root) enters the grinding chamber via a screw conveyor, where high-speed rotating blades reduce it into fine particles. 2. **Pneumatic Classification Chamber**: The powder is carried by airflow into the classifier. Oversized particles are sent back to the grinding chamber for reprocessing, while fine particles pass through. 3. **Cyclone Separator & Dust Collector**: The fine powder flows into the cyclone separator for collection, while residual dust is captured in the dust box, ensuring a clean working environment. 4. **Integrated Control Panel**: The electrical control unit allows operators to adjust speed, airflow and fineness settings with precision, supporting both manual and automated operation.
