    In order to determine the relationship among energy consumption of rock and its fragmentation, dynamic strength and strain rate, granite, sandstone and limestone specimens were chosen and tested on large-diameter split Hopkinson pressure bar (SHPB) equipment with half-sine waveform loading at the strain rates ranging from 40 to 150 s−1. With recorded signals, the energy consumption, strain

    DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT

    Horizontal shaft impact crusher These break rock by impacting the rock with hammers/blow bars that are fixed upon the outer edge of a spinning rotor. Here the rotor shaft is aligned along the horizontal axis. The input feeded material hits the rotating hammers of the rotor and due to this sudden impact it breaks the material and further breaks the material by throwing it on to the breaking bar
