The customer in Bangladesh is engaged in the production of high-purity quartz powder, which is widely used in electronic materials, glass manufacturing, and precision casting. As market demand for finer and purer quartz powder increases, the customer planned to build a compact ultrafine grinding production line to achieve stable micronization and high product purity.
Material Characteristics and Technical Challenges
Quartz (SiO₂) is a mineral with high hardness (Mohs hardness 7), strong wear resistance, and excellent chemical stability. During grinding, it tends to cause severe abrasion to equipment and can easily introduce metallic impurities such as iron, which degrade product purity. Therefore, maintaining high purity while achieving a fine particle size of around D50 ≈ 3 μm became the key technical challenge of this project.
Equipment Selection
After multiple discussions and test comparisons, the customer selected the EPIC Powder MQW10 Jet Mill. This model features a full ceramic lining design, effectively preventing metal contamination and ensuring high purity and whiteness of the final quartz powder.
Key Advantages:
- Contamination-free operation: All parts in contact with the material are made of zirconia ceramics, eliminating Fe or Cr contamination.
- High-efficiency ultrafine grinding: Utilizes compressed air for particle-on-particle impact, requiring no mechanical grinding media.
- Precise particle size control: Consistently achieves D50 ≈ 3.19 μm, with a narrow particle size distribution and excellent particle shape.
- Compact and easy to maintain: Small footprint, simple operation, and convenient maintenance — ideal for small-scale, high-end powder production.
