When manufacturers and mineral processors search for reliable equipment to make high-purity, ultrafine kaolin powder, the core demand lies in zero metal contamination, narrow particle size distribution, high whiteness, and stable mass production performance. After nearly 19 years of specialized R&D in powder processing, JACAN Powder Equipment has developed a full set of precision ultrafine grinding systems tailored exclusively for kaolin ore, widely recognized as the top choice for high-end ultrafine kaolin production worldwide.
Why ordinary grinding mills fail kaolin processing requirements
Common industrial pulverizers with metal liners and steel grinding media have obvious drawbacks for kaolin:
- Steel wear introduces iron and titanium impurities, severely reducing kaolin whiteness and purity, making the powder unqualified for coating, papermaking, lithium battery filler and plastic masterbatch applications.
- Agglomerated kaolin particles cannot be fully dispersed, resulting in wide particle size ranges and poor dispersibility in downstream resins.
- Single grinding units lack supporting classification and modification functions, requiring extra separate equipment and raising overall production costs.
- Conventional mills cannot meet ppm-level impurity control standards required by top global mineral enterprises like Imerys, Sibelco, CATL and BASF.
For high-value ultrafine kaolin, only dedicated all-ceramic precision ultrafine grinding systems can solve these pain points comprehensively.
JACAN’s all-ceramic ultrafine kaolin grinding mill: the optimal solution for ultrafine kaolin powder
Founded in 2007, JACAN Powder Equipment has focused on ultra-fine mineral grinding technology for 19 years, serving over 1,200 clients across more than 50 countries, with its kaolin processing equipment covering over 37% of top-tier kaolin powder manufacturers globally. Its core ultrafine kaolin grinding mill integrates four core processes to deliver premium ultrafine kaolin powder.
1. Ultra-purification & pretreatment module
Before grinding, the system adopts advanced magnetic separation and physical refinement to break raw kaolin ore lumps and fully expose internal impurities. It strictly controls iron and titanium contaminants down to ppm levels, laying a foundation for ultra-high whiteness finished kaolin powder and eliminating preliminary impurity interference in the grinding stage.
2. All-ceramic media precision milling core (the core advantage of JACAN kaolin mill)
Different from traditional metal-lined grinders, JACAN’s ultrafine grinding mill uses full ceramic lining and ceramic grinding media. This design completely avoids secondary metal contamination during grinding. The intensive grinding function thoroughly disperses hard kaolin agglomerates while fully retaining the original high purity of kaolin ore, stably reaching micron-level ultrafine fineness without damaging the natural sheet morphology of kaolin particles.
3. High-precision air classification system
Equipped with matched high-efficiency air classifiers, the mill system disperses micro-powder agglomerates thoroughly, screens out coarse particles, and achieves narrow particle size distribution. Optimized particle morphology greatly improves the dispersibility of ultrafine kaolin powder, which is critical for downstream papermaking coating, paint, plastic filler and refractory material production.
4. Functional surface modification unit
As an optional supporting module matched with the ultrafine grinding mill, the customized surface molecular modification device coats kaolin powder uniformly during processing. It significantly enhances the compatibility and bonding force between kaolin powder and polymer resin, upgrading the mechanical strength and thermal stability of finished plastic, rubber and coating products.
