Abstract：A mixed stirring method with solid medium in a sealed chamber was proposed to improve the mixing uniformity of multi-component micropowder.The vibration mixing method was adopted with agate ballas the mixing medium.EDEM was used to simulate the mixing uniformity of the mineral and powdered catalyst with particle size of 50μm to 150μm.The influence of the number of stirring medium and the inclination angle of mixing tray on the mixing uniformity was analyzed.A vibration test bench was developed and the vibration mixing test was carried out.The results show that proper vibration stirring and proper vibration inclination angle can significantly improve the uniformity and efficiency of micro-powder mixing.When an agate ball is added into the crucible, the turning angle of the mixing tray is 20～30 degrees, and the mixing time is about 2.5 minutes.The mixing uniformity can meet the test requirements, the mixing effect is good, and the mixing efficiency is high.The experiment verifies the correctness of the simulation model, and provided theoretical support for mass mixing production operation.
