【Abstract】 The aim of this article was to increase grain’s purity ratio and decrease cleaning loss ratio of drum device for cleaning short stem. Taking spiral and cylinder screen of drum device as research objects, using the method of regression analysis to test, we can establish the mathematical models of cleaning and sorting attributes of the device. The best movement parameters had been obtained by multi objects optimal design technique. The influences of movement parameters of cleaning and sorting attributes of the device were analyzed. The grains purity ratio can reach 99.6%. The cleaning loss ratio can reach 0.11%.更多还原
