The three-ring medium-speed micro-powder mill is one of the most advanced dry-process non-metallic ultrafine grinding equipment in China. The crushing of materials and the classification of powders occur within the same machine body but operate independently. This design offers a compact structure, adjustable product fineness ranging from 1400 to 3000 mesh, easy maintenance, low energy consumption per unit product, and cost-effective investment. The entire process, from crushing and classification to finished product, takes place in a closed system, and the dust-laden gas is treated by dust removal equipment, ensuring no pollution. It is an ideal green and environmentally friendly piece of equipment.
