This review article focuses on a particle flowability during vibrating discharge and introduces a research for the effects of discharging vibration conditions and coating structures on improving the flowability in a smaller particle admixing system. In the research, main and admixed particles were mixed in various mass ratios to obtain coating structured particles, and the discharge particle flow rates of the coating structured particles were measured. In addition, coverage diameter, surface coverage ratio, and coverage height of the admixed particles on the main particle surfaces were obtained by image analysis of scanning electron microscopy and scanning probe microscopy. As a result, the admixing mass ratio and coating structure of admixed particles that gave maximum flowability were affected by the maximum value of the vibration acceleration.
