The ACEY-VPM-400ML Planetary Ball Mill Machine performs dry grinding, suspension grinding, or operations in inert gas environments. Beyond comminution, this versatile equipment handles mixing and homogenizing of emulsions and pastes, as well as mechanical alloying and activation in material research. With its compact design, comprehensive functionality, high efficiency, and low noise operation, it serves as an ideal solution for research sample preparation in institutes, universities, and enterprise laboratories—capable of processing four samples simultaneously. When equipped with vacuum ball milling tanks, it can grind samples under vacuum conditions. Applications span Geology, Mining, Metallurgy, Electronics, Construction Materials, Ceramics, Chemical Engineering, Light Industry Medicine, and Environmental Protection.
