Impact Crushers
benefits of impact crushing
Impact crushers – like horizontal shaft impactor (HSI) and vertical shaft impactor (VSI) models – have an unfair reputation in some parts of the aggregate industry. Usually, it’s because they’re being misapplied or poorly maintained.
When utilized correctly, impact crushers are absolute rockstars! They produce some of the highest value, highest quality material in the aggregates industry.
Selecting between HSI and VSI crushers
Unlike the compression or squeezing action produced by jaws and cones, impact crushers (HSI and VSI) break rocks with rapid strikes. This action generates two primary benefits: high reduction ratio and precise product shaping.
Cubicle-shaped rocks are strong and have much greater particle-to-particle contacts, making them ideal for asphalt, concrete, limestone and other applications shown below.

8 Benefits of Impact Crushing
1.
Shape rocks into uniform, high value cubicle products.
2.
Products require less binder or cement for asphalt and concrete.
3.
Remove unwanted material from feed (benefication).
4.
Lower capital cost than compression crushers.
5.
Spacious interiors improve accessibility for maintenance.
6.
Limited recirculation of already crushed material.
7.
Good performance for damp, clay-contaminated or sticky feeds.
8.
Very suitable in fine crushing applications.
