The work aims to review the research progress of relevant superfine powder filling and metering technology to provide scientific research basis for further research and development of superfine powder filling and metering packaging machinery. Through the analysis and summary of the present research situation and research results at home and abroad, the superfine powder’s properties were introduced, the relevant technology of filling, metering and packaging process of superfine powder and the factors affecting the filling effect in the filling and metering process of superfine powder were generalized, and the new filling and metering technology of superfine powder and its development trend were summarized. The filling and metering machinery of superfine powder was similar to that of the ordinary powder. Volumetric and weighing type metering machines were used. Weighing type metering was the mainstream in the market. Three technical problems to be solved urgently in superfine powder mechanical packaging were environmental pollution, packaging precision and packaging speed. Cleaning, precision and high speed of superfine powder filling and metering machinery are the development trends of superfine powder mechanical packaging.
