Market Pressure:<\/strong> The EU REACH regulation limits heavy metals to <10 ppm; automotive coatings require D99 < 1.5 \u03bcm and \u0394E < 0.3. The air classifier mill integrates grinding and classification<\/strong> in one unit. The high-speed rotating grinding disc generates strong impact, shear, and friction forces to disperse and pulverize pigment agglomerates. An internal precision turbine classifier performs real-time particle separation. The classifier immediately discharges qualified fine powder and returns coarse particles to the grinding zone for further processing. For pigments, particle size and distribution are key performance parameters:<\/p> With the development of high-tech fields such as new energy vehicles (NEVs) and high-definition (HD) displays, higher demands are being placed on the functionality, weather resistance (durability), and environmental compatibility of pigments.<\/p> The Air Classifier Mill, with its characteristics of high efficiency, precision, and low contamination, has become a crucial piece of equipment for achieving ultra-fine processing and high dispersion in the pigment industry.<\/p> Leveraging its years of experience in fine powder processing, EPIC Poeder<\/a><\/strong> offers total solutions to the pigment industry, spanning from laboratory research to industrial production. This helps clients enhance pigment quality, reduce energy consumption, and realize the stable and controllable manufacturing of high-performance color materials.”<\/p> <\/p>
