Vertical Shaft Impact Crusher
The main way to adjust the reduction ratio of the VSI and GS is by adjusting the rotor rip speed. This can be done by a variable speed drive or by changing the motor/crusher pulleys. At a rotor tip speed of 45m/s, crushing is at its lowest, but we have a high capacity. At 82m/s, crushing is at its highest, but we have a lower capacity.
