A Study on the Development of Stabilized High Speed Blade for Ultra Fine Pulverizer

This study is to develop the quieter and less vibration blade according to high speed and the problem of durability shortage in impact blade of hammer mill which is produced and sold by Suin Tech Co. Ltd. To solve the problem, we investigated the natural frequency of the system and the mode shape of natural vibration frequency. We predicted the resonance of the structure and the mode shape according to the vibration and also suggested design specification of the blade. At last we evaluated the system according to acquired design basis and verified the design condition.
