Abstract
In order to solve the problems of low automation degree of micro-high-precision powder addition in the laboratory, large influence of human factors and high labor cost, a set of screw feeding and weighing integration device is designed to realize the automatic addition of powder agent, the mechanical structure and speed of screw feeding are closely related to the accuracy of powder addition, and the discrete element method (EDMEM) is used to simulate spiral powder feeding at different speeds, and the simulation analysis shows that the spiral speed is positively correlated with the motion speed of particles. The spiral velocity is inversely correlated with the density of the particles.
