Our objective is to design various components of an Impact crusher like drive mechanism, shaft, rotor, hammers, casing, and discharge mechanism which will be useful in minimizing weight, cost and maximizing the capacity and also do their analysis. Impact crushers involve the use of impact rather than pressure to crush materials.

Critical speed (nk) is the rotational speed at which acting dynamic forces cause a machine component (e. g. shaft, rotor) to vibrate at its natural frequency (also referred to as intrinsic frequency, fi) and can even result in resonant vibrations throughout the entire machine and pump set. This effect has the potential to damage fast rotating machinery but can be minimised when such rotational
