    2011-5-10 · An impact crusher can be further classified as Horizontal impact crusher (HSI) and vertical shaft impact crusher (VSI) based on the type of arrangement of the impact rotor and shaft. 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.


    2016-4-23 · 3. OPERATING MECHANISM This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive.
