Investigation on the Motion States of the Hammers while Hammer Mill Steady Running by High-Speed Photography
Actual motion states of the hammers while hammer mill steady running is an important analysis basis for the dynamic characteristics of the hammer mill rotor and the wear mechanism between hammers and hammer pivots. To investigation the actual motion states of hammers, a high-speed photography was used in this paper to record the instantaneous states of the hammers. And comparison analysis on the pictures recorded at three different working speeds was made, the results showed that, for each hammer on the hammer mill, there exists random static deflection phenomenon; and for all hammers, there exist chaos phenomena with relative rest positions in range of a certain angle.
