Abstract On the basis of fully considering the movement modes of the grinding ball in a vibration mill grinding tube, a bilateral impact calculation model named "grinding medium-wheat bran-grinding medium" was proposed based on the similarity principle.This model overcomes the shortage of the single side impact calculation model which can not simulate impact shear.At the same time, the material parameters of the model and the solution setting of the finite element simulation calculation were given.On this basis, the finite element numerical simulation was carried out on the movement characteristics, quality characteristics and crushing forms of wheat bran breaking properties by using the LS-DYNA.The results show that the effect of milling medium on the crushing properties of wheat bran is significant.In terms of the motion characteristics, the higher the impact speed of the grinding ball, the better the crushing performance of wheat bran.However, the greater the impact angles of the grinding ball, the worse the crushing performance of wheat bran.In terms of quality characteristics, the greater the density parameters of the grinding ball, the better the crushing performance of wheat bran; the greater the diameter of the ball, the greater the contact force; the greater the contact area of the wheat bran, but the contact number will be reduced.In the aspect of crushing form, the difference between impact shear and impact extrusion in contact force, contact time and contact area is small，but the effective plastic strain of bran center unit caused by impact extrusion is greater than that of impact shear.For large size bran, impact extrusion should be applied as the main form of crushing; and for small size bran, impact shear should be used.The above research preliminarily found out the effect of grinding ball on the crushing performance of wheat bran, and provided a new way to explore the influence law of material crushing performance of vibration mill comprehensively.
