Product Description: The planetary ball mill is an essential device for mixing, fine grinding, sample preparation, nanomaterial dispersion, new product development, and small-scale production of high-tech materials. This product has small size, full functionality, high efficiency, and low noise, making it an ideal equipment for scientific research institutions, universities, and enterprise laboratories to obtain microparticle research samples (four samples can be obtained simultaneously in each experiment). Equipped with a vacuum ball milling tank, it can grind samples in a vacuum state.
