High Pressure Micro-Powder Grinder: On basis of long-term experiments and improvement, having absorbed the latest mechanical technology of Germany and Japan, we successfully design the high pressure micro-powder grinder which is comparable to the Yet Mill. And it not only solves the difficulties of classifying the ultra-fine powder but also solves the high cost problem of Jet Mill for domestic clients. Its output and nenergy consumption both meet the national standards,ranking advanced level at home and abroad,which wins much praise and approval. It is suitable to grind more than 500 kinds of materials with the Mohs scale of hardness below 6, such as Kaolin, limestone, calcite, marble, barites, gypsum, ferric oxide, aluminum hydroxide, pigment, clay, coal, activated carbon, feldspar, talc, carbon black, figuline etc. The fineness of the product ranges from 500 mesh（0.025mm）to 2500 mesh（0.005mm），some can even reach 3500 mesh（3.55micrometres）.
