Ultra-fine Pulverizer Walnut Shell Air Classifier Mill
The BSP Ultra-fine Pulverizer is purpose-built for processing challenging materials, with walnut shells being a prime example. The machine's core assembly consists of a robust body frame, drive motor, screw feeder, grinding chamber, cyclone separator, bag filter, induced blower, and a centralized control cabinet. This design has made it the preferred choice for pulverizing high-fiber content, heat-sensitive, and brittle materials across the food, chemical, and pharmaceutical industries.
Operating without a screen, this air classifier mill achieves the desired product fineness—ranging from 30 to 2500 mesh—by precisely adjusting the classifier wheel speed, allowing for continuous, uninterrupted production.
Main features:
1. Integrated Classification for High Efficiency: The machine's compact and rational design integrates an internal air classifier. By combining grinding and classification into a single step, it eliminates the need for external screens and significantly reduces energy consumption.
2. Ideal for Heat-Sensitive Materials: The integrated draft fan creates a continuous airflow that efficiently dissipates heat generated during the grinding process. This makes the mill exceptionally well-suited for heat-sensitive materials, such as walnut shells and other organic matter.
3. Superior Adaptability and Uniform Particle Size: The system offers exceptional adaptability to different material types and ensures a narrow particle size distribution. The finished product is consistently uniform, with fineness easily adjustable from 30 to 2500 mesh.
4. Extended Service Life of Wear Parts: All primary grinding components are manufactured from high-grade alloy tool steel. This ensures exceptional durability, greatly extending the service life and replacement cycle of wear parts, even when processing abrasive materials like walnut shells.

FAQ
Q: What will be delivery time?
A: Usually,the lead time is 30 work days.
But please contact our sales to confirm, the delivery time is affected by many reasons.
Q: Is the powder size adjustable?
A: Yes, the powder size can be changed by setting the parameter of inverter.
For example, if you want finer powder, you can try 25 Hz, if not fine enough,then try 30HZ,35Hz...etc
Q: How many countries have you exported?
A: Till 2025, we have exported machines to more than 90+ countries. Including USA, European countries,Japan, South American countries,Australia,New Zealand,and lot of Middle-east Asia countries,Southeast Asian countries and Africa.
