DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT

This type of crusher is generally used with soft materials like coal, seeds or soft metallic ores. The mechanism applied here is of Impact loading where the time of application of force is less than the natural frequency of vibration of the body. Since the hammers/blow bars are rotating at a very high speed, the time for which the particles come in contact with the hammers is very small, hence
