Energy considerations in compressive and impact crushing ...

2008-8-1  The particle breakage in the VSI is achieved through rock against rock impact. This breakage mechanism is more random compared to the cone crusher, and there is a probability that some stones pass through the crusher unbroken. In addition, the impact breakage has been shown to produce more fine material than what is observed in a cone crusher.

What Is A Vertical Shaft Impactor (VSI) Primer? Stedman ...

VSI Benefits. When it comes to producing materials such as aggregate for road making, VSI crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or ...

Modeling and Optimization of a Vertical Shaft Impactor

2015-12-9  Vertical Shaft Impact crushers have been used for a long time to reduce the size of particles and to give particles a cubical shape profile. Very few investigations have been performed on the inner workings of the VSI crusher and even fewer attempts have been made to model the particle breakage and collisions that occur inside it.

Impact Crusher - an overview ScienceDirect Topics

Breakage commences when rock enters the rotor, and is thrown centrifugally, achieving exit velocities up to 90 m s −1. The rotor continuously discharges into a highly turbulent particle “cloud” contained within the crushing chamber, where reduction occurs primarily by rock-on-rock impact, attrition, and abrasion.
