Project Background and Challenges

The Australian customer produces high-purity quartz powder used in advanced glass, electronic components, and specialty materials.
Their main challenges were:

  • To achieve fine, uniform particle size with excellent morphology for precision applications.
  • To maintain ultra-high purity with zero metallic contamination throughout the production process.

Traditional steel-lined mills tend to cause iron contamination over time, which is unacceptable for electronic-grade quartz. To address these challenges, the customer adopted Epic Powder’s ceramic-lined ball mill and ceramic classifier wheel system, ensuring both purity and performance.

Epic Powder Solution

Epic Powder engineered a ball mill- classification integrated system that combines high-efficiency grinding and precise classification for quartz powder. The system achieves fine particle control while maintaining continuous and stable production.

Key Features:

Ceramic Lining for High Purity:
The mill chamber, grinding media, and liner are all made of high-purity alumina ceramics, completely preventing Fe, Ni, or Cr contamination.

  • High-Precision Ceramic Classifier Wheel:
    Equipped with a ceramic impeller and variable frequency control, the classifier maintains a precise D50 = 7.5 μm cut point with narrow particle size distribution.
  • Efficient and Stable Performance:
    Optimized ball mill speed, filling rate, and airflow parameters enable continuous operation with 1.5–2 t/h throughput and low energy consumption.
  • Continuous and Automated Operation:
    The production line includes automatic feeding, real-time particle monitoring, and smart classification control, ensuring consistent quality with minimal maintenance.

Results and Customer Feedback

After commissioning, the system achieved excellent stability and high classification accuracy. The final quartz powder showed high purity, brightness, and consistent fineness.
The customer praised the equipment’s energy efficiency, low maintenance, and high yield. The project significantly enhanced their product quality and market competitiveness.
