Energy considerations in compressive and impact crushing of rock
The rock particles accelerate and impact the surrounding bed of rock that is formed during operation. They also impact rock particles that do not pass through the rotor, but fall down outside it. This material is called bi-flow or cascade. Crusher manufacturers recommend operating the VSI crusher with 10–15% of the total as bi-flow.
