The planetary ball mill is an essential device for mixing, fine grinding, small sample preparation, new product development and small-batch production of high-tech materials. Our company's planetary ball mill is small in size, fully functional, highly efficient, low in noise and pollution-free. It is an ideal equipment for research institutions, universities and enterprise laboratories to obtain research samples (2-4 samples can be obtained simultaneously in each experiment), and is equipped with a vacuum ball mill jar This machine can grind samples under vacuum conditions. It can be used for both dry and wet grinding. The grinding time can be set by yourself and it can be spewed by frequency conversion. The speed accuracy is 0.2 revolutions per minute. The feed particle size is ≤10mm for soil materials and ≤3mm for other materials. The minimum output particle size can reach 0.1μm The materials of the micron (even nanometer level) ball milling jars can be selected from: agate, alumina, corundum ceramic, zirconia ceramic, silicon nitride ceramic, silicon carbide ceramic, stainless steel, high wear-resistant steel, manganese steel, nylon, polytetrafluoroethylene, polyurethane, cemented carbide, crystal glass, etc. Balls available for selection include: agate, alumina, zirconia, silicon nitride, silicon carbide, stainless steel, high wear-resistant steel, manganese steel, nylon, polyurethane, cemented carbide, etc.
