What is an impact crusher?
Impactors are versatile crushers used in every stage of crushing. Unlike jaw and cone crushers, which use compression to crush rock, impactors rely on velocity and impact to reduce the size of the material. Because this type of crusher doesn’t generate the same amount of force as compression crushers, it is best suited for less abrasive softer rock like limestone.
Their large feed opening and high reduction ratio also makes them well suited for crushing concrete and asphalt for recycling.
Types of Impact Crushers
There are two configurations of impact crushers: Horizontal and Vertical Shaft Impact Crushers
Horizontal Shaft Impactors (HSI) can be used in any crushing stage, but their ability to accept a larger feed size and provide a high rate of reduction makes them ideally suited for primary crushing.
Vertical Shaft Impactors (VSI) are typically positioned after the primary crushing stage where a specific size and shape are required. They produce a consistent cube-shaped material that provides excellent compaction, making it ideal for making concrete, asphalt, base gravel, and specialized products like manufactured sand (MF).
How Impactors Work
HSI crushers
The crushing chamber of HSI’s contain blow bars attached to a fast-spinning rotor. When the feed enters the primary crushing chamber, it comes into contact with the blow bars which smash the rock and launch it at the apron. The impact created by this collision breaks the material into smaller pieces.
The impact of the bars continually crushes this material until it becomes fine enough to pass through the apron plate gap, and enters the secondary crushing chamber where it is crushed further and shaped into a high-quality end product and is discharged from the crusher.
VSI crushers
A VSI relies on the velocity of material inside the crusher and impact to reduce the size of the material. Rock is fed into an accelerator at the centre of the crusher that uses centrifugal force to sling the material against an outer ring, lined with anvils. The size of the crushed rock is determined by the speed of the rotor.
