An orthog onal experimental design with three factors at two levels was adopted to set up a mathematical model describing effects of selected parameters on experiment criterion .The optimal technological parameters for ginkgo biloba pulverizing with planetary ball mill were determined through multi-objective no-linear optimization method.with grinding drum rotation speed 484r/min, ratio of ball to ginkgo biloba 8.5,grinding time1.2h.With which the effect of ginkgo bi-loba superfine grinding was best .the result perfectly match the theoretical values , that prove the reliability of the numeri-cal model.
