How to Make High Quality Pueraria Root Powder: From Coarse Crushing to Ultra-Fine Milling
Pueraria Root Powder is made from the root of Pueraria lobata, a traditional medicinal herb known for its rich content of isoflavones, especially puerarin. These natural compounds are valued for their antioxidant, cardiovascular, and anti-inflammatory benefits. However, raw Pueraria roots are often large, dense, and fibrous, which limits their solubility and absorption.
To produce high-quality Pueraria Root Powder suitable for use in capsules, tablets, teas, and other health products, the roots must go through a carefully controlled milling process. This process not only improves bioavailability but also ensures consistent particle size and stable quality.
In this article, we focus on how YDCS Coarse Crusher and YDWF Air Classifier Mill work together — from coarse crushing to ultra-fine milling — to create fine, uniform Pueraria Root Powder that meets modern production standards
Étape 1: YDCS series Pueraria Root Concasseur grossier: 5-20mm Pueraria Root Granules
Because Pueraria roots are large and fibrous, pre-treatment is essential before ultra-fine grinding. The YDCS coarse crusher is designed to efficiently process tough herbal materials like Pueraria root, reducing them into uniform 5–20 mm particles. This step ensures smooth feeding, stable operation, and improved efficiency in the subsequent milling stage, directly enhancing the quality of Pueraria Root Powder.

Structure and Working Principle
The YDCS coarse crusher mainly consists of a feeding port, crushing chamber, discharge port, and an optional dust collector. Inside the chamber, fixed and movable knives work together to shear and impact the material. The crushed pieces are then discharged by centrifugal force. By changing the inner screen, the final particle size can be precisely controlled between 5–20 mm — an essential pre-processing stage for high-quality Pueraria Root Powder production.

Step 2: YDWF Series Pueraria Root Air Classifier Mill:80-320 Mesh Pueraria Root Poudre
After coarse crushing, the pre-sized Pueraria root granules are ready for ultra-fine milling. The YDWF Air Classifier Mill performs precision grinding to produce uniform Pueraria Root Powder with a particle size range of 80–320 mesh (approximately 180–45 μm). This step is critical for improving solubility, absorption, and overall product consistency in pharmaceutical and nutritional applications.

Structure and Working Principle
The YDWF Air Classifier Mill is composed of the main milling chamber, connected pipes, cyclone discharge unit, dust collector system, and blower.
In operation, pre-sized Pueraria root granules enter the grinding chamber through the feeding funnel. High-speed rotating blades shear and crush the material into fine particles. The particles then pass to the classification chamber, where both centrifugal and air forces act. Particles larger than the set classification size are returned to the grinding chamber for further milling, while finer particles are carried by airflow to the cyclone separator and dust collector. This closed-loop process ensures uniform particle size and high-quality Pueraria Root Powder.
Main Features of YDWF Series Pueraria Root Air Classifier Mill
- Integrated Grinding and Classification:Combines milling and air classification in a single system, producing consistent, uniform ultra-fine Pueraria Root Powder with particle sizes ranging from 80–320 mesh (approximately 180–45 μm) to meet diverse product requirements.
- Dust-Free Operation:Equipped with high-efficiency bag filters and automatic pulse dust cleaning, ensuring a safe and clean working environment.
- Efficient Discharge:Rotary discharge valve provides reliable air sealing and smooth material output from the collection system.
- Easy to Clean and Maintain:Smooth, disassemblable internal structure with no dead corners supports hygienic operation for food and pharmaceutical standards.
Necessary Accessories: Industrial Air Cooling Chiller
Pueraria roots are dense and fibrous, which can result in increased temperature during ultra-fine milling if not properly cooled. Therefore, an Industrial Air Cooling Chiller is essential to control the temperature, protect the active compounds in Pueraria Root Powder, prevent powder agglomeration, and ensure stable, high-quality production. This setup enables effective low-temperature milling, preserving the bioactivity and uniformity of the powder.

Conclusion
The production of high-quality Pueraria Root Powder involves a carefully controlled two-step milling process. First, the YDCS coarse crusher pre-treats the dense and fibrous Pueraria roots, reducing them to 5–20 mm granules. Next, the YDWF Air Classifier Mill performs ultra-fine milling under controlled conditions, producing consistent powder with particle sizes between 80–320 mesh (45–180 μm). With the support of an Industrial Air Cooling Chiller, low-temperature grinding preserves the active compounds, prevents powder agglomeration, and ensures stable, high-quality output. Together, these steps provide an efficient and reliable solution for producing premium Pueraria Root Powder for capsules, tablets, teas, and other health products.
