Abstract:A fireworks disc pelletizer was developed. Based on the theory of powder into tablets, the influence of the four factors including atomization pressure and flow of the adhesive, rate of powder supply, distance between hopper nozzle and discharge opening,polishing time to the quality of micro pill was gotten by single factor experiments, thus process parameters were determined. Then orthogonal experiment was carried out. The best process parameters was finally gotten based on the particle size classification on granulation samples gotten by orthogonal experiment.
