Cosmetic-Grade Kaolin Processing Equipment: A Guide to Milling and Purification
We provide a wide range of mills — including Raymond mill, trapezoidal mill, vertical mill, ultrafine mill, and ball mill, obtained ISO9001 international quality certification, EU CE certification, and Customs Union CU-TR certification. Suitable for processing minerals such as limestone, phosphate, quicklime, kaolin, talc, barite, bentonite, calcium carbonate, dolomite, coal, gypsum, clay, carbon black, slag, cement raw materials, cement clinker, and more.
The discharge range of these mills can be adjusted to meet specific processing needs, typically from 80-400 mesh, 600-3250 mesh, and can achieve the finest particle size of up to 6000 mesh(D50).

Cosmetic-Grade Kaolin Processing Equipment: A Guide to Milling and Purification
Kaolin, a naturally occuring white clay, is a cornerstone ingredient in the cosmetics industry. Its gentle absorbency, smooth texture, and ability to impart opacity make it ideal for foundations, face powders, masks, and blushes. However, transforming raw kaolin into a product suitable for high-end cosmetics requires precise milling and thorough purification. The journey from a coarse mineral to a luxuriously fine, contaminant-free powder demands specialized equipment that prioritizes ultra-fine grinding, iron removal, and operational hygiene.
The Critical Steps: Milling and Purification
The primary goal in cosmetic kaolin processing is to achieve a consistently ultra-fine particle size (often down to d97 ≤ 5μm or finer) while maintaining the material’s natural whiteness and purity. Any metallic contamination, especially from iron, can introduce discoloration, rendering the batch useless for cosmetic applications. Traditional grinding methods like ball mills can be inefficient for such fine grinding and often introduce significant iron wear from the grinding media itself.
Modern processing lines therefore rely on advanced, contamination-controlled milling technologies. The equipment must feature robust dust collection systems to maintain a clean environment and often incorporates magnetic separators at various stages to extract metallic particles. The grinding mechanism itself should be designed to minimize metal-on-metal contact, preserving both the equipment and the purity of the kaolin.
Recommended Equipment for Superior Results
For producers aiming for the highest cosmetic-grade standards, selecting the right mill is paramount. Based on its exceptional performance in ultra-fine powder production with minimal contamination, we highly recommend our MW Ultrafine Grinding Mill.
This machine is specifically engineered for customers who need to make ultra-fine powder. A key feature for cosmetic applications is its design: there are no rolling bearings or screws inside the grinding chamber. This eliminates major sources of iron pollution and prevents machine damage from loose screws, ensuring the product’s whiteness and integrity. Furthermore, it is equipped with an efficient pulse dust collector and muffler, making the entire production process cleaner and quieter, which is essential for operating to GMP standards.
The MW Mill boasts a cage-type powder selector with German technology, allowing precise fineness adjustment between 325-2500 meshes, achieving a precise d97≤5μm in a single pass. Its higher yielding and lower energy consumption—40% higher capacity than jet mills and 30% lower system energy consumption—make it not only a superior technical choice but also an economically smart investment for high-volume production.
Beyond Milling: The Integrated Approach
While the MW Mill excels at the grinding stage, a complete processing line often begins with jaw crushers and dryers. For operations looking for a highly integrated solution that combines grinding, drying, and classifying in a single unit for slightly less demanding fineness or larger feed sizes, our LM Vertical Grinding Mill presents another excellent option. Its vertical structure integrates multiple functions, significantly reducing the plant’s footprint and overall investment cost.
Ultimately, achieving cosmetic-grade kaolin is a symphony of precision engineering and meticulous process control. Investing in the right milling equipment, like the MW Ultrafine Grinding Mill, is the most critical step in ensuring a flawless, high-value product that meets the stringent demands of the beauty industry.
