Due to its extremely high surface energy, zinc oxide readily forms severe hard agglomerates during production. Conventional ball-milling processes are not only time-consuming but also struggle to achieve sub‑micron particle size distribution. The cell mill, employing vertical high‑speed shear technology, offers a new approach to ultrafine grinding of zinc oxide. Within the equipment, the combined action of high‑speed rotation and powerful stirring generates immense mechanical shear stress in an instant, directly breaking up agglomerates. “ Tear ” Rather than simple impact-induced fragmentation.
This treatment method can not only significantly reduce D50 Particle size—and, more importantly, the ability to optimize particle morphology distribution—helps prevent the formation of irregularly shaped particles caused by excessive grinding. For specialty zinc oxide products that demand exceptionally high whiteness and fineness, cell‑type mills can elevate fineness to industry‑leading levels while maintaining pristine purity, thereby laying a solid foundation for subsequent chemical reactions or coating dispersion.
