A new method of adlay shelling was presented to design a sheller. The adlay shelling technology that a mutual friction between grinding wheel and nylon wheels horizontally placed shell adlay was used. Moreover, the three-dimensional structure of sheller was designed, and the main parts of machine were also checked. Further-more, in order to prevent the occurrence of resonance, ANSYS modal analysis of the body and the frame were carried out. The pro-totype of Adlay shell test results showed that the raw material processing capacity was 0.3 t/h, the shelling rate was greater than 95%, the whole ...
