does the speed of the crusher affect the crushing

Vertical Shaft Impact Crusher

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. The size of the crusher product also depends on the feed size, the throughput, the crushability of the material, and whether or not the cascade feature is used.
