In this paper the structural features of the hammers mill are analyzed. The statics and the vibration characteristic of its frame are investigated with the ADAMS software. A discrete model of hammers mill39。s rotor arranged in different hammer forms was analyzed by way of dynamic simulation with virtual prototype technology. The result that is similar to facts was deduced. The conclusion indicated that the rotor with interlaced or symmetryinterlaced hammer form has better balance and the former is with good stability because of its equal load on each bearing. Rotor is an important assembly of hammers mill. This research utilized Pro/E to carry out threedimensional modeling of the parts of hammer mill’s rotor, virtual assemble, model analysis, and motion emulation. Designers can modify the parts easily by changing size parameters, and also can observe forming, position relation of parts and motion state of the rotor.
